CSS Custom Properties Simplify Gradient Transitions

CSS custom properties have a problem most developers don't think about. The browser stores them as raw strings. It has no idea if --color is a color, a length, or a banana. That's why you can't transition a gradient - the browser sees two opaque strings and just swaps them instantly. I spent way too long working around this. Pseudo-elements with opacity fades. JavaScript-driven interpolation. All to get a gradient hover transition that should be simple. Then @property clicked for me. You register a custom property with a type - <color>, <angle>, <percentage> - and suddenly the browser can interpolate it. Gradient transitions, rotating conic gradients, animated borders. All in pure CSS. 3 things that surprised me: 1. You transition the custom property itself, not the background. The gradient rebuilds every frame with interpolated values. 2. Setting inherits: false scopes a variable to one element. Child elements get the fallback instead. Useful for design tokens. 3. Invalid values fall back to your defined initial-value instead of breaking the declaration. Type safety in CSS. It's been in Chrome and Edge since 2020, Safari since 2023, and Firefox caught up in July 2024. No reason not to use it now.

Server-Side Rendering for Dummies Server-Side Rendering, often called SSR, means the server generates the HTML for a page before sending it to the browser. Instead of the browser building everything using JavaScript, the server does the heavy lifting first. How normal React rendering works... With plain React, most apps use client-side rendering. Flow looks like this: 1. Browser loads a mostly empty HTML file 2. JavaScript bundle downloads 3. React runs in the browser 4. UI gets rendered That is why you sometimes see a blank screen for a moment. How Server-Side Rendering works... With SSR, frameworks like Next.js render the page on the server first. Flow looks like this: 1. User requests a page 2. Server runs React code 3. Fully built HTML is generated 4. Browser receives ready-to-view content The page appears almost immediately. Then JavaScript hydrates it and makes it interactive. Simple mental model... - Client-side rendering → Browser builds the page. - Server-side rendering → Server builds the page first. That is it !

Ever spent 30 minutes fixing your CSS… only to realize the problem wasn’t CSS at all? That happened to me today. I was making my website responsive and wrote a media query like this: @media (max-width:768px) Everything looked perfect. But on my phone… nothing changed. After a lot of confusion, I realized the real problem was a missing line in HTML: <meta name="viewport" content="width=device-width, initial-scale=1.0"> Without this tag, mobile browsers assume your website is built for desktop screens. So they render the page at around 980px width and simply scale it down. Which means your media queries like "max-width:768px" never trigger on mobile. One small line. One big lesson. Sometimes in web development, the bug isn’t in your code logic .... it’s the tiny thing you forgot to add. #WebDevelopment #Frontend #HTML #CSS #LearningInPublic

Safari has 7 new CSS pseudo-classes for media. They help you style video players without using JavaScript. Apple added these new tools for web developers. You can now change how a media player looks based on its state. You can do this using only CSS. You do not need JavaScript to check the player status anymore. Here are the seven new CSS pseudo-classes you can use: - :playing applies when the media plays. - :paused applies when the media stops. - :seeking applies when the user skips ahead. - :buffering applies when the media is loading. - :stalled applies when the connection is too slow. - :muted applies when there is no sound. - :volume-locked applies when the device controls the volume. These tools make building custom video players very fast. For example, you can easily show a loading spinner when the video is buffering. Other browsers like Chrome and Firefox do not support this yet. We will have to wait to use these tools on every browser. What do you think about these new CSS features?

Interesting web debugging moment Today I opened a problem on LeetCode and the page looked completely broken. All the text and elements were visible, but the UI styling was gone no layout, no design, just raw content. At first glance it looked strange because: • The page content loaded • Images and text were visible • But the CSS styling was missing This actually highlights an interesting aspect of how the web works. Why this happens Browsers load a webpage in layers: 1.HTML loads first – this defines the structure of the page 2.CSS loads next – this applies styling and layout 3.JavaScript runs – adds dynamic behavior If the CSS files fail to load (network glitch, CDN issue, blocked request, or caching problem), the browser still renders the HTML structure. So you end up seeing the “raw skeleton” of the website. Possible reasons this happens • CDN or asset server failed • CSS file request blocked or timed out • Browser cache conflict • Network interruption during resource loading • Content Security Policy issues Small reminder for developers Modern websites depend on multiple resources loading from different servers. When one layer fails, the browser still tries to render whatever it has. Seeing the unstyled version of a complex platform like LeetCode was actually a fun reminder of how the web works under the hood. Sometimes bugs are just the internet showing you the raw architecture of the web. Curious have you ever seen a big website load like this? #webdevelopment #frontend #debugging #javascript #css #html #leetcode #softwareengineering

🎉 New Article 🎉 Beyond The Blur: A Quick Guide to the CSS Backdrop-Filter Property 7 years ago I built a simple playground for backdrop-filter when Firefox made it available behind a flag. I finally wrote the article I always intended to. This guide covers what backdrop-filter is, all 9 filter functions, how to combine them, and why filter order actually matters (spoiler: it produces different results). Plus an updated interactive CodePen playground to experiment with everything. Check out the full article: https://lnkd.in/dDxFz_-z #CSS #WebDevelopment #FrontendDevelopment #WebDesign

Most developers think a webpage appears instantly. But your browser is actually doing 6 heavy engineering steps in milliseconds ⚡️ When you open a site in LinkedIn, Google Chrome, or Mozilla Firefox, this is what REALLY happens behind the screen: 🔹 Step 1 — HTML → DOM Browser converts HTML into a tree structure (Document Object Model). Think: building the skeleton of the page. 🔹 Step 2 — CSS → CSSOM All styles are parsed and organized. Think: deciding colors, fonts, layouts. 🔹 Step 3 — DOM + CSSOM → Render Tree Structure + styles combine. Only visible elements remain. 🔹 Step 4 — Layout (Reflow) Browser calculates exact positions & sizes. “Where should each element sit?” 🔹 Step 5 — Paint Pixels get colored. Text, borders, shadows, images — everything drawn. 🔹 Step 6 — Composite Layers merge using GPU → Final page appears on screen. And here’s the twist 👇 Every time JavaScript changes something… → DOM updates → Layout recalculates → Paint happens again That’s why heavy JS can slow websites. 💡 Golden rule for performance: Use transform & opacity (cheap) Avoid width/height/margin changes (expensive) Understanding this pipeline changed how I write CSS & JS forever. Because great developers don’t just code… They understand what the browser is doing behind the scenes. #WebDevelopment #Frontend #JavaScript #CSS #BrowserInternals #Programming #Learning #codebegun

♻️ Why normalize.css still matters in modern web development A lot of devs think CSS normalization is “old school” and unnecessary. That’s a mistake. And it costs real time in real projects. Browsers still ship with different default styles. Margins, headings, forms, buttons, line-heights — they’re not consistent across Chrome, Safari, Firefox, Edge. This is where tools like normalize.css and modern resets come in. What normalization actually gives you: ✅ Predictable base styles ✅ Cross-browser consistency ✅ Fewer layout bugs ✅ Cleaner component CSS ✅ Less “why does it look different in Safari?” debugging ✅ More control over design systems 🎓 Normalize vs Reset (important difference): Reset.css → removes almost everything (aggressive, blank slate) Normalize.css → keeps useful defaults but standardizes behavior (smart baseline) Normalize doesn’t fight the browser — it aligns it. 🧠 Modern alternatives: modern-css-reset sanitize.css custom minimal resets in design systems framework resets (Tailwind Preflight, Bootstrap Reboot) Different tools — same goal: 👉 controlled rendering environment 👉 predictable UI behavior 👉 scalable CSS architecture #WebDevelopment #FrontendDevelopment #CSS #NormalizeCSS #DesignSystems #UIEngineering #WebStandards #CrossBrowser #ScalableCSS #CleanCode  

I built a VS Code extension that shows you exactly where your CSS is used (and finds dead CSS) Hey everyone, I built CSS Reference Counter and Peek. It natively scans your project (HTML, JSX, Vue, Svelte, etc.) and gives you: Inline Counts: CodeLens shows exactly how many times a class is used right above the CSS rule. Dead CSS Scanner: Automatically finds unused selectors and highlights them with yellow warnings. Click to Navigate: Ctrl+Click a class in your JSX to jump straight to the CSS file. It's super lightweight, caches to disk for instant load times, and handles SCSS nesting correctly via PostCSS. Check it out on the marketplace: "css-reference-counter" Let me know what you think!

🔥 90% of Websites Struggle with This Basic CSS Concept I've seen many websites struggle with a basic concept: understanding the CSS box model. Imagine you're sending a gift to a friend. You wrap the gift in paper, and that's like the content area. But then you add some extra space around the paper, like a ribbon or a bow, and that's like the padding. The problem arises when you try to add a border around the gift, and suddenly it looks like the ribbon is overlapping with the border. That's because the border is added to the outside of the padding, not inside. Here's a quick example: Let's say you have a paragraph of text with a width of 200px, padding of 20px, and a border of 5px. If you don't understand the box model, you might think the total width is 200px. But in reality, the total width is 200px , content, + 2 x 20px , padding, + 2 x 5px , border, = 250px. Did this help? Save it for later. Check if your website has this problem by inspecting your elements in the browser's dev tools. #WebDevelopment #LearnToCode #CSS #BoxModel #WebDesign #CodingTips #TechEducation #FrontendDevelopment #WordPress #HTML #JavaScript #ResponsiveDesign #WebDesignTips #CSSbasics #CodingForBeginners
