SCSS – Write Smarter Stylesheets!

Today’s learning session was all about making styling easier, smarter, and scalable — thanks to SCSS, the CSS preprocessor that makes a developer’s life so much simpler.

Instead of repeating styles or cluttering large CSS files, SCSS brings in features that traditional CSS lacks — like variables, nesting, and functions — all while compiling down to plain CSS behind the scenes.

🧪 What I Practiced in SCSS:

  • Variables: Saved common values like colors and font-sizes

  • Nesting: Organized styles better by writing parent-child relationships directly

  • Mixins: Created reusable blocks for padding, shadows, etc.

  • Functions: Used custom and built-in SCSS functions for cleaner logic

  • Partials and Imports: Broke my styles into smaller manageable files

 SCSS in Interviews – Key Questions & Answers

 1. What is SCSS?
 2. SCSS vs CSS – What’s the difference?
 3. What are mixins and how are they useful?

 Frontend Interview Topics Revisited

Besides SCSS, I also revised some key frontend interview questions:

🔹 CSS

  • Specificity: How styles are prioritized when multiple rules match

  • Box model: Content → Padding → Border → Margin

  • Flex vs Grid: One-dimensional vs two-dimensional layout

🔹 JavaScript

  • Hoisting: Variables and functions are moved to the top of their scope before execution

  • Closures: Functions that remember their outer variables

  • Async/Await: Modern way to handle asynchronous operations more cleanly than Promises

🔹 React

  • Props vs State

  • Hooks like useEffect, useMemo

  • Controlled vs Uncontrolled Components

 Gracias:

I’m grateful I finally took the time to dig into SCSS properly. It genuinely speeds up styling and helps keep the code clean, especially in big projects.
Also, reviewing frontend interview questions refreshed many concepts I thought I knew — repetition really is the key.

Excited to use SCSS in my next React project and keep improving!

Revising GitHub CLI commands (Day1)

GitHub CLI Revision Today I marked the beginning of my revision journey, and I started with GitHub CLI.  I revised all the commands using GitHub Docs and Git Cheat Sheet. Also I revised from GeeksforGeeks also.  Practiced some basic core commands like:  git init, git clone git add, git commit  git push, git pull  git branch, git merge, git checkout Also Created a test repo and tried to pushed the commits using CLI.  I read full explanations from GeeksforGeeks.  Git Workflow -  Also understand how git workflow-> from staging area, working directory.  GitHub also helps in versioning controlling  Challenges -  Sometimes, merge conflicts led to minor confusions like head and current change but exploring little more from Chatgpt and documentation helps in figuring it out.  Gracias- Grateful to have a mentor for guiding me  I'm thankful for this opportunity to revise more and understanding this concept more in a better way ab...

JavaScript Deep Dive + React Review (Day-5)

 JavaScript & React – Interview Prep Mode Today was all about preparing for frontend interviews , and I focused heavily on reviewing core JavaScript and React concepts from the shared 150+ question set. What I Covered: JavaScript Topics: Completed all JS questions from the set Focused particularly on: Promises & Callback functions Closures and how they work under the hood Async/Await and handling asynchronous logic These topics were a bit tricky at times, but revisiting them helped me gain more confidence and clarity. React Topics (Partially Covered): Reviewed around 90 questions Focused on core concepts: useState , useEffect , useMemo Type-related questions and common hook usage I still need to complete the remaining React questions, but the progress so far has been good i learnt more about these topics than i knew before.  What I Learned: Revisited how closures work and why they’re important in functional JS. Understood as...
