Sharing my learnings: Critical Rendering Path - In simple terms, it’s the process the browser follows to convert HTML, CSS, and JavaScript into pixels on the screen. Here’s how it works: - Browser receives HTML from the server - HTML is parsed → DOM is created - CSS is parsed → CSSOM is created - DOM + CSSOM → Render Tree Browser renders in steps: - Style calculation - Layout - Paint - Composite The goal? Show content to the user as fast as possible (First Contentful Paint). #frontend #webperformance #javascript #react #learninginpublic

Still writing simple UI popups in JavaScript? For basic overlays like tooltips and hints, the native HTML Popover API can reduce extra code. • No JavaScript needed for basic open and close • Built-in keyboard handling and focus behavior • Click outside to dismiss with popover="auto" • Best for simple, declarative UI patterns Supported in modern browsers, making it a practical choice only for simple UI patterns Follow for more practical dev tips. #HTML #WebDevelopment #Frontend #CodingTips #ModernWeb #Syncfusion

2025 was the year CSS started replacing your JavaScript. Customizable <select> -- no more Radix or Headless UI dropdowns. Invoker commands -- open a dialog with zero JS. CSS carousels -- native dots and arrows with ::scroll-marker. Scroll-state queries -- detect if a sticky header is stuck, in CSS. Each of these features eliminates a JS library you're probably still importing. Here are the 6 CSS features from 2025 that change how you build UIs. Which one are you most excited to use in production?

https://pretextjs.dev A new frontend library called Pretext (March 2026) is trying to change how we handle text layout. Current approach: Render → Measure → Re-render Pretext approach: Calculate → Render once Instead of using DOM measurements like getBoundingClientRect(), it lets you: • Predict text size before rendering • Avoid layout shifts • Reduce re-renders Useful for: • Chat/message UIs • Infinite scroll lists • Dynamic cards • Multilingual layouts It works without the DOM and can run on the server as well. Still new, but interesting direction for performance-focused UIs. #frontend #javascript #reactjs #webperformance

I’ve seen senior developers get tripped up by this. CSS Specificity. One of those concepts you ‘know’… until it bites you in production. Here’s the thing most developers learn CSS by copying and pasting. Or directly using with libraries like Tailwind and Bootstrap. So when styles stop working, the reflex is: → Add !important → Add an ID → Give up and use inline styles And then the codebase turns into a specificity war nobody wins. Here’s what actually matters: → Inline styles beat everything (except !important) → IDs (0,1,0,0) beat classes (0,0,1,0) every time → !important isn’t a selector it overrides the cascade entirely → The more specific your selector chain, the harder your CSS is to maintain The real skill isn’t memorizing the hierarchy. It’s structuring your CSS so you rarely need to fight it. Design systems, BEM, utility-first (Tailwind) — they exist largely to prevent specificity wars at scale.

👉 Day 79 – Frontend Foundations Revisited ✨ Today was all about revision and reinforcement. I revisited the core building blocks of frontend development — HTML, CSS, Bootstrap, and JavaScript (up to DOM) — to strengthen my fundamentals and ensure clarity before moving deeper. 🔸 Revised semantic HTML and how structure impacts accessibility. 🔸 Practiced CSS styling, layouts, and responsive design principles. 🔸 Revisited Bootstrap utilities for faster UI building. 🔸 Reinforced JavaScript basics and DOM manipulation concepts. 🌱 Reflection – Revision is not repetition; it’s refinement. Each revisit uncovers new insights and strengthens confidence. Just like debugging code, revisiting fundamentals helps debug our understanding. ⚡ Day 79 reminded me that mastery comes not from rushing ahead, but from revisiting and reinforcing the basics that power everything we build. #Day79 #FrontendDevelopment #HTML #CSS #Bootstrap #JavaScript #DOM #CodingJourney #10000Coders #LearnInPublic #100DaysOfCode

This JavaScript library completely changed how I think about text. I’ve been working on my portfolio recently using the Pretext library by Cheng Lou and it’s absurd. Pretext is a JavaScript library that lets you break out of traditional CSS and DOM constraints and build truly dynamic UI. Instead of rendering everything and asking the DOM what happened, with Pretext you compute and measure everything first, then render once. This shift feels small, but it opens the door to more innovative, dynamic interfaces that aren't limited by typical layout rules.

While working on a recent project, I ran into an issue where CSS changes weren’t being applied especially when the project started getting heavier or when I was rapidly updating the UI. This seems to happen quite often in older Tailwind CSS projects as well, where styles don’t reflect properly or files appear to be missing. In those cases, this simple command usually fixes it: "rm -rf .next && npm run dev" It clears the build cache and restarts the development server from scratch. A small command, but a very useful one when things start behaving unexpectedly. #nextjs #tailwindcss #webdevelopment #frontenddeveloper #softwareengineering #buildinpublic #javascript #devtips #webdevUK

🧮 Calculator Project — HTML, CSS & JavaScript Built a fully functional calculator with a clean, modern UI and smooth interactions. This project strengthened my JavaScript logic, DOM handling, and responsive layout skills while recreating a practical, real-world tool. ✅ Features 🔸Basic arithmetic operations 🔸Clear/Delete functionality 🔸Real-time input and results 🔸Responsive, minimal interface A simple tool turned into a solid exercise for mastering frontend fundamentals. #FrontendDevelopment #HTML #CSS #JavaScript #WebProjects #PortfolioProject #UIUX

Watch My Calculator Project in Action! I recently built this calculator using HTML, CSS, and JavaScript, and here’s a quick demo of how it works What I worked on: • Implementing JavaScript logic for calculations • Handling user input and button events • DOM manipulation for dynamic updates • Creating a clean and responsive UI 💡 This project helped me strengthen my understanding of how frontend logic works behind the scenes. Every small project is a step forward, and I’m excited to keep building and improving my skills. 💬 I’d love to hear your feedback! #WebDevelopment #JavaScript #Frontend #Projects #LearningJourney #BSCS
