As a Microverse Student in the last time, I have been struggling with some HTML and CSS projects. They challenged me to learn new features of these technologies all the time. My projects were made gradually trying to follow good practices but none was as striking for me as the use of semantic HTML.

CSS units are very important when creating a responsive website and you might wonder which one to use considering we have several CSS units. I had the same issue while working on a project, so I did some research on it. In this article, I will show you the most suitable CSS units to use for responsive design.

It is common knowledge that frontend development is essential for creating responsive, engaging, and visually appealing websites and applications.

Every beginner should first start with the basics. In case of CSS, the basics are learning the box model. Before proceeding with learning any other CSS concepts, this is the one you should master first!

Recently I wanted to add a multi-step form to my site. Since my site runs on Hexo, a static page generator, I had some doubts about how to execute this task. I already had a static form on my site, and I didn’t want to spend too much time on the development of features like steps, show/hide logic or validation.

Fetching data asynchronously with Redux Thunk was always too much of a hassle for developers until Redux Toolkit arrived with so many promising features.

It's been a long time since Hypertext Markup Language (HTML) showed up to become the basis of the web. Since that time, many things have changed, and some features of the HTML files went from desirable to negative. Thus, a cryptic markup or an obfuscated source code once considered useful things to avoid unauthorized copies, seems to be a nonsense in the fight for positioning in search engine results that we live in today.

If you're trying to learn CSS Flexbox, I bet you've spent some time watching a few tutorials on YouTube. Maybe you've seen the Wes Bos series, that’s a great one. Maybe you're bi-lingual and found some helpful content in your native tongue. Most technical content on the internet is in English, as we know. Yet, sometimes I find some amazing content in my native Portuguese. (Like this remarkably simple to understand tutorial on Flexbox). Finally, how can you not have resorted to the Interneting Is Hard tutorials?

There’s a foundational question that every project starts with: accept the freedom to roll your own solutions along with the burdens that go with it, or take the chance to use sensible defaults that allow you to move quickly, but hide a multitude of decisions and set you on a prescriptive path.

Fetching data from internet is one of the most common operations that every developers should master. In Flutter, this operation is pretty straightforward. In this post we will learn how to handle data from fetching to displaying it on our mobile apps.

Autocomplete Search Component With React and TypeScript

Hi everyone! Today I want to talk about fast TS compilation. There are a lot of tips and tricks about TypeScript code style. But not about compiler performance.

Web security is a topic that is often overlooked by frontend developers. When we assess the quality of the website, we often look at metrics like performance, SEO-friendliness, and accessibility, while the website’s capacity to withstand malicious attacks often falls under the radar. And even though the sensitive user data is stored server-side and significant measures must be taken by backend developers to protect the servers, in the end, the responsibility for securing that data is shared between both backend and frontend. While sensitive data may be safely locked in a backend warehouse, the frontend holds the keys to its front door, and stealing them is often the easiest way to gain access.

The best way to use SVG icons is to create an SVG sprite. Here's an easy tutorial for beginners and pros alike.

Developing an admin area for your React web application can be very time-consuming. And it is just as important as designing all of the front-end pages. Both admin area of your web-application and the pages themselves must be pixel-perfect, fully responsive and have mobile-first and user-friendly web design.

There are a lot of React pre-made components out there that promise infinite scroll functionality. The problem with that is that sometimes they are not tailored to fit your specific needs, especially if you are using the newly featured React-Hooks to create functional components all across your application. These pre-made components work well with class components, but they have not been updated to work with the state-of-the-art functional hook-components.

How to achieve better type safety and code quality by improving types in TypeScript's standard library.

In this article, we will consider several interesting hacks that allow you to use custom properties for what would seem impossible without preprocessors or JS.

The React Context API provides a way to share properties that are required by many components (e.g., user settings, UI theme) without having to pass a prop through every level of the tree (aka prop drilling). Although Vue.js does not provide the same abstraction out of the box, in this article, we’ll see that in Vue 3, we have all the tools we need to replicate the same functionality quickly.

Web page styling has evolved over the years, from just styling HTML elements to a well thought, organized and scalable approach. Implementing CSS style on a web page can be a complex task with many different display presentations available on modern websites. Paying closer attention to how smaller parts of the webpage fit into the whole design flow of the webpage can be an important tool for efficient development.

This article is a prequel of sorts to my earlier 110% Complete JWT Authentication with Django & React - 2020 article. That article covers how to get started with JWT authentication in a typical React and Django Rest Framework project, and it does that well enough. There's just one major annoyance with it - I couldn't figure out how to get live reloading working! So for every change made to the frontend, we had to shut down the dev server, rebuild the React bundle, and start it up again. Talk about tedious!

Do you enjoy building fast and professional looking pages using React and Bootstrap? What if I tell you that there is a more efficient way (and in my opinion, that looks more professional) to build websites.

Typically, when we build a single-page application, the frontend and the backend are living in two very separate worlds that are connected with a web API. Even if they are implemented with the same language (JavaScript), they cannot communicate directly using this language. They need something else in between, so we build a web API (REST, GraphQL, etc.), and that complicates everything.

Nowadays, as a webdeveloper, you rarely build anything from scratch: your daily job mostly consists of integrating various Javascript libraries together. If you are building a web app you are most likely going to use some framework like React, Vue or Angular for your front-end. To transmit and manage the data you will be using Redux or GraphQL. For the backend, there will be Express and probably Loopback. Then you need to cover everything with tests, so Jest, Mocha or Jasmine must be present too. Finally, there will be UI frameworks like Bootstrap and maybe some charting tools. I have already counted at least 7 core libraries and all of these are in a single project! And what about underlying technologies like Javascript itself, Node.js and, probably, Typescript? Well, that’s a lot!

If you are aware of the latest developments in .NET for the last couple of years, you must have heard the buzzword ‘Blazor’ quite often. It is a revolutionary client-end User Interface framework developed by Microsoft’s mighty ASP.NET Expert team.

As the world becomes increasingly digitized, the demand for front-end developers is only going to increase.

Step-by-step process from creating an Embedded widget using Shadow DOM and Typescript.

The React JS dev team announced some exciting changes several months ago - React would be getting a "Concurrent Mode". Essentially this would allow React to perform multiple UI renders concurrently. Of course, JavaScript is single threaded and true concurrency is an illusion, but the new features will allow web apps (and Native Apps once these features hit React Native) to be much more responsive and snappy than they are now with less effort and custom code from the developer to make this happen.

Hi, fellow RxJS streamer! 👋

React library provides us two built-in hooks to optimize the performance of our app: useMemo & useCallback. At first glance, it might look like their usage is quite similar, so it can get confusing about when to use each. To clear that confusion, let’s dig in and understand the actual difference and the correct way to use them both.

The Pointer Lock API (formerly called Mouse Lock API) provides input methods based on the movement of the mouse over time (i.e., deltas), not just the absolute position of the mouse cursor in the viewport. It gives you access to raw mouse movement, locks the target of mouse events to a single element, eliminates limits on how far mouse movement can go in a single direction, and removes the cursor from view. It is ideal for first person 3D games, for example.

Hey there 👋Thanks for checking my first Hackernoon article. My name is Vova and I'm a self-taught front-end engineer. I started learning front-end two years ago and was lucky to land my first job in a tech startup. Getting the first job is (very) challenging but the startup I applied to wanted to give equal chances to the professionals of all levels.

So the last 1.5 years I was playing with React, Redux, Webpack, fetch, Node.js, Express.js Backend, Webhooks.…You know, in a startup you are wearing different hats. I was making 20+ landing pages, setting up A/B tests, helping the marketing team to make automation and eventually doing some design tasks.

That's fun and I always enjoyed design tasks, even if they were small. So it became asking myself, what other people are using for making design tasks?

Here is what I got from a small Twitter research:

My first intro to positioning with grid and flexbox started with a course on CSS3. Three months after saw me in a coding boot-camp for remote software developers.

I am Javier, a guy starting in this world of web development. My background is the filmmaking business, especially the video edition. I am writing this article to help guys like me that are learning web development or everyone that considers the design or the “look” of a webpage one of their passions. Back in my days of video-editor, one cool thing that I found in the software video and design editors was the ability to blend two images or more in order to display better. So if you just put an image in a given color background you can start to discover how the different values can make interesting looks.

Do you often find yourself banging your head against the wall when trying to make your page responsive? I sure did for a long time, that was before I became familiar with the grid system. I had already seen and used grid a few times but I was a little intimidated by the huge amount of properties that it has to offer, but today I’m pretty comfortable creating layouts with just CSS Grid, so in this article, I want to show you what I think are the most important properties that you can use in CSS grid to make your web page fully responsive.

The 3 key decisions that makes Vite faster than Webpack.

In single-page apps that use the Vue Router, it is common to create a path parameter that changes the behavior of a route.

This article will help you to start a path to front-end development. In the last 10 year’s I didn’t pay any attention about programming and the way websites built. About 2 years ago, I started to spend more than 12 hours every day working as a remote tester for several platforms.

I have been working in the automation field for more than a decade, and have seen automation tools evolve in unique ways. During the earlier years, when AI technologies weren’t prevalent, I remember how our automation team faced particular and unavoidable challenges which we, at that time, thought were some of the trickiest to resolve from our end.

If you haven’t used a precompiler before, you are about to fall in love. When you first learn CSS, you learn it stands for Cascading Style Sheets, which is pretty accurate. Whatever property you change twice, it will be overridden by the latest line. Because of this, CSS involves a lot of repetition and specification. Either via classes, IDs or selectors you have to show the browser exactly what you want to style. But what if I told you this could be easier? You could write a very specific CSS file without repeating so much. When I learned about this, I thought I was dreaming. When I learned how to do it, I promised myself I would never go back to simple CSS if I could help it.

CSS, Cascading Style Sheets, is a style sheet language that is simple and easy to learn. It is basically about how to represent HTML elements on the screen. It is mainly used for adding styles to web pages. It is one of the favorites of developers and designers for adding styles to web pages. So, today we will be talking about the 11 most asked questions on CSS.

Looking through the admin template market you can easily conclude that this market is saturated. It’s observed in the number of templates, the amount of developers and (what is of the most important) a bunch of articles of «Best templates …(and here year, description or whatever goes)». And the amount of template becomes bigger and bigger every year. After reading several articles you may find out that to remember the name of the template you have liked is not (just believe us, really “not”) an easy task (of course, if you keep a template page in a browser tab it’s much easier, but don’t forget that RAM is limited and your browser may already keep 40+ tabs).

Filled with repetitious code that looked as messy as spilled spaghetti.

Cascading Style Sheet (CSS) Grid Layouts is the most important and powerful layout system available in CSS. It’s built inside a two-dimensional
system, meaning it can handle both columns and rows. You can build a
true grid layout by applying CSS rules both to the grid element and
the parent element.

We keep changing how we style the web, but the real problem isn’t CSS. It’s how we build around it.

When building apps that rely on data from an API, two things are essential: we want our data to be fresh, and we want it fast. The stale-while-revalidate caching pattern helps us to strike a balance between both.

Imagine you have six images on your home page. You might proceed with loading the images separately. After all, they are six different images and to be used in six different places. And you might be right ... from your perspective. You also know that loading six different images will force the browser to make six different HTTP requests to the server. And each time it makes a request, a few milliseconds gets added to your page loading time. That's bad news if you have fifty images.

Design systems are interdisciplinary by nature. They are built and consumed by designers and developers, therefore it is important for common terminologies to exist to support the communication between these two disciplines and other related actors.

Recently, I had the incredible honor to work with an individual who was a Survivor of Domestic Violence. This was all part of a business "hackathon."

The power of the Web is in its universality.
Access by everyone regardless of disability is an essential aspect.

An application can only be as good as the features it is providing for its end-users. Every developer toes the line between indiscriminately adding gems and building new functionality themselves. When time is of the essence, these are the gems I reach for:

A basic introduction to Variable Fonts.

This blog covers an analysis of why redux state is immutable and how you should go about modifying state in your Redux applications

Most mobile and cross-platform web developers have encountered the problem at some point: you need your web app to scale neatly to the device screen size, regardless of which of the many thousands of devices there are out there, but your units only have one design layout width, mainly mobile. Or perhaps you need to create a per-device stylesheet for a truly scalable cross-platform UI, and want to use a scaled version of an original to base it upon. In either case, converting everything by hand is laborious and inconvenient.

That is how I used to think two months ago before I start an HTML & CSS course at Microverse.

You’re going to hate me for saying this, but I actually like being on-call. Honestly! It’s taught me more about frontend quality than any bug tracker ever did.

Here are some recommended settings for a good result doing your first steps creating a PWA using QCObjects:

Getting feedback from the audience has always been important to me. Luckily, there are plenty of form services available in the wild such as SurveyMonkey and TypeForm. Anyone can integrate these into their sites quite easily. For a few use cases, I choose Google Forms because 1) I already have an account, 2) It's easy to integrate, 3) The responses can be populated into Google Sheet natively, and 4) I trust Google with (some of) my data. However, the default look and feel don't go well with any non-material design websites.

Among all the concepts you have to understand in CSS, Specificity is a tricky one; and, it may be the reason why that font-size is not being applied to the element you're trying to target.

WeAreDevelopers World Congress is one of the biggest IT events in Europe. This year I got to be one of the participants.

I recently took some serious time to improve my skills in front-end HTML and CSS.

Creating a robust toolkit is crucial for a successful migration of existing apps and the smooth adoption of new micro-frontends in the future.

DNS resolution is the first thing that happens when a request is made to a remote server. It is a process of finding the computer-friendly address of the remote server using a human-friendly domain name.

There is a myth that the easiest thing about web development is building a web-page layout. Based on this, some developers decide not to waste time on learning a competent approach to layout. And it’s in vain. There are many ambiguous moments in the layout, which are worth paying attention to.

CSS stands for “Cascading Style Sheets.” It is a formatting language that allows us to visually improve our HTML tags (size, color, font, etc.). As the name suggests, it does it by cascading.

When you start this way of learning the fundamentals of HTML and CSS you can find a lot of web sites that can help you to know HTML semantic tags, how to name classes, how to write rules for tags, events, animations... and even how to use more advanced models as FlexBox and CSS grid.

This content drop presents the new aspect-ratio property on CSS.

A little while ago we wrote about the float property. So, now is a good time to explain the clear property.

A practical guide to semantic design tokens for multi-platform UI.

Building website these is one thing, building an accessible and useable website is another thing entirely as it requires some expertise and use of accessibility tools.

A code should be organized. That’s the fact and I think is a very good one for the opening of the text about nesting.

In my last Coding for Gamers post we talked about replicating the hunger meter in The Long Dark. Today’s post is about replicating a feature from Hellblade: Senua’s Sacrifice. Hellblade is one of the most harrowing journeys into a mentally ill person’s mind that I have ever seen in a video game. If you haven’t played it, I highly recommend checking it out. You don’t even have to worry about getting addicted because the game has a concrete beginning, middle, and end. One of the unique aspects of Hellblade is a mini puzzle game that involves finding a shape in nature that matches a shape carved into the various runes in the world.

REST APIs are commonly used in web development. They are programming interfaces that web apps use to 'talk' to each other. They are used to access features and data. 'REST' (Representational State Transfer) is a concept that defines the APIs properties. This article will focus on the use of web-based APIs to retrieve data from a database.
