Day 1 – Understanding the Cascade Many frontend teams underestimate how much time they could save by better understanding the CSS Cascade. The Cascade is not just a set of rules, but the core mechanism that determines how browsers make decisions. Those who understand how Importance, Origin, and Specificity interact write CSS that is more consistent, predictable, and resilient in the long run. The Cascade is not an opponent to be outsmarted – it is a system to work with. Solid CSS starts not with frameworks or tools, but with understanding these foundations. #CSS-Advent-Calendar #CSS #Web-Development https://lnkd.in/ePCBq6Us

Just spent my morning fiddling with Tailwind CSS and React... and honestly, where has this been all my life? 😅 Remember the days of writing endless custom CSS files that turned into absolute spaghetti code after a few months? Tailwind's utility-first approach is like a breath of fresh air. Instead of this: ```css .my-special-button { background: blue; padding: 1rem; border-radius: 0.25rem; /* and 15 more lines of properties */ } ``` You just write: ```html <button className="bg-blue-500 p-4 rounded"> ``` And done! ✅ The integration is dead simple too - just a few npm commands and you're ready to go. I've been using it on a couple of client projects lately, and the development speed is properly impressive. Anyone else made the switch to Tailwind? Or are you still riding the CSS-in-JS train? Drop me a DM - always keen to chat about what's working in your front-end stack!

End-of-year reflection, validation Frontend input validation is not enough, it improves user experience. Backend validation protects the system. HTML can be changed. JavaScript can be disabled. The backend validation is your friend to have secure system. Always do both, but never rely on frontend alone.

Day 2 of my Frontend Development journey 🚀 Today was all about getting comfortable with HTML basics and understanding how web pages are structured. ✅ What I learned today: HTML structure (<!DOCTYPE>, <html>, <head>, <body>) Common tags like headings, paragraphs, lists How browsers read and render HTML Practice: Created a basic HTML page using different tags 📌 Key takeaway: A strong foundation makes everything else easier to learn. Day by day, step by step — staying consistent #FrontendDevelopment #HTML #WebDevelopment #LearningInPublic #Day2 #CodingJourney

Ever wondered why some websites feel slow or laggy? It’s often due to how browsers process HTML, CSS, and JavaScript known as the Critical Rendering Path. In that Notion link , I discuss five major frontend fundamentals: -How your page loads step by step -Why CSS and JS can block rendering -What Core Web Vitals (LCP, INP, CLS) mean for your users -Lazy loading, caching, and other optimizations to make your site fast and smooth Check out the full breakdown and learn how to speed up your website’s performance! https://lnkd.in/gkh2Ungy

I realised that frontend performance isn’t about writing more code- it’s about writing less of the wrong code. Here , I documented my learnings on: i) Bundle Splitting: loading only what the user needs first instead of shipping one massive JS file ii) Critical CSS : rendering above-the-fold content instantly by eliminating render-blocking styles iii) Essential State: identifying the minimum state required and deriving everything else iv) Reducer Pattern: managing complex UI updates with predictable, centralised state logic v) Windowing: rendering only visible items to keep large lists fast and responsive All focused on real-world browser behaviour, Core Web Vitals, and scalable UI design.

Day 13 of #100DaysOfCode I didn’t code or post for the last two days. Had a few things with deadlines to catch up on. But today I’m back — and continuing where I left off. Today I completed Section 25 – CSS Cascade Layers (@layer). This section was interesting because it didn’t introduce something entirely new, but instead gave a better way to manage something CSS already had — the cascade. Important clarification first: CSS layers are not visual layers like z-index. They’re layers we write in CSS, to control how rules win or lose in the cascade. What I learned about Cascade Layers: – They help organize CSS into logical groups (reset, libraries, components, themes, overrides, etc.) – Rules inside a layer compete only with rules in the same layer – Specificity and order still apply, but within that layer only – Rules in different layers don’t fight each other using specificity This means I can now control which group of styles should win without rewriting selectors or playing specificity games. Layers can be defined in different ways: – Using @layer blocks – Declaring layers upfront without rules – Assigning imported CSS files to specific layers Another powerful thing: CSS written outside of any layer automatically gets the highest precedence. So I can safely layer third-party CSS and override it cleanly without hacks. Key takeaway for me: Nothing about the cascade rules has changed: – origin & importance – specificity – order of appearance What has changed is that layers are now part of the cascade ordering itself. For normal rules → the latest layer wins For !important rules → the earliest layer wins This gives explicit, intentional control — instead of relying on accidental order or overly complex selectors. Overall, this section felt less about “new tricks” and more about writing CSS that scales and stays maintainable. Slow progress, but solid learning. #100DaysOfCode #CSS #WebDevelopment #Frontend #LearningInPublic #DeveloperJourney

Are we still using CSS tools out of habit? Native CSS has come a long way. Many features that once required polyfills are now baseline across browsers. You may not need Tailwind, Sass, or PostCSS anymore. Yes, context matters—but for many teams, the defaults may now be enough. Honest question: if you were starting a project today, would you still add these tools… or reach for native CSS first? #WebDevelopment #FrontendDevelopment #CSS #WebDesign #SoftwareEngineering #DevTools #Frontend #Programming #TechDiscussion

🚀 Your website is shipping 40% dead code. Here's how to find it in 60 seconds. Most developers don't know about Chrome DevTools' Coverage tab. It's a game-changer for performance optimization. The Problem: Every extra KB of unused CSS/JS kills your load time, tanks your Lighthouse score, and costs you conversions. The Solution: Chrome's Coverage tab shows you EXACTLY what code never runs. Here's how: 1️⃣ Press F12 (or Option+Command+I on Mac) to open DevTools 2️⃣ Hit Ctrl+Shift+P (or Command+Shift+P on Mac), type "coverage" 3️⃣ Click the reload button 4️⃣ See the damage: Red = unused code What you'll find: → Third-party scripts loading 500KB of unused code → CSS frameworks where you use 10% of the styles → Legacy JavaScript that hasn't run in months Quick wins: ✅ Code split your bundles ✅ Lazy load non-critical resources ✅ Enable tree-shaking in your build config ✅ Delete truly dead code The Coverage tab is built into Chrome. No extensions needed. No excuses. Try it on your site right now. I guarantee you'll be shocked by what you find. #WebPerformance #WebDev #JavaScript #FrontendDevelopment #ChromeDevTools #PerformanceOptimization #WebDevelopment
