css-100

🎨 My version of the 100 Days of CSS challenge.

Objective

For the next 100 days, I'm committing to tackle at least one CSS challenge a day. My goal is to refine my CSS skills, explore diverse styling techniques, and delve into crafting pure CSS artwork and animations.

A version of my completed daily challenge can be found on my own dedicated website at css100.aniqa.dev. In addition to that, I'll be submitting CodePens to the official challenge website where my progress will also be tracked.

Project Structure

This project includes a series of completed challenges, with the first 50 utilizing HTML, CSS, and occasionally JavaScript for necessary functionalities, and the final 50 utilizes the same except with SCSS to practice more complex styling.

General Webpage Resources

• The /src directory holds all files related to the general structure and styling of the webpage, as well as the main script for loading each entry
• The /public directory contains all production-ready code, bundled and optimized using Webpack

Challenges Directory

Each challenge is self-contained in its own directory within /entries, labeled by day number (e.g., /001, /023). Within each challenge's directory, you will find:

• style.css or style.scss: Contains all the CSS or SCSS styling specific to the challenge
• content.js: Returns the HTML markup needed for the challenge
• script.js: Holds any JavaScript code required for the challenge's functionality
• README.md: Provides insights and learning takeaways from each challenge

Note

To prevent class naming conflicts, each challenge will be wrapped with a unique parent class corresponding to the day of the challenge (e.g., .day-001, .day-023). This convention allows for the use of descendant selectors to target elements within a specific challenge's scope, ensuring that styles do not bleed across challenges.
