Week 3 Summary: HTML Core & Self-Taught CSS
Learning the rules, breaking the limits.

​ 1. The HTML "Skeleton" 
​I mastered the fundamental structure that every website needs:
​The Guard: <!DOCTYPE html>—The "whistle-blower" that tells the browser to stay modern.
​The Roots: Organizing code into the <head> (metadata/brain) and <body> (the visual part).
​The History: Learning about Ada Lovelace (the 1st programmer) and Charles Babbage (the "Father" of computers).
​Special Tags: Explored the <ins> (inserted text), <u> (underline), and the <bdo> (backwards text) tags.
    
​ 2. The CSS "Skin" (Self-Taught Progress)
​While we haven't started CSS in class yet, I've begun styling my projects manually to make them stand out:
​The Box Model: Understanding how Padding (inside space) and Margin (outside space) keep elements from bumping into each other.
​Backgrounds: Learning how to use background-image and url() to change the vibe of a page.
​Flexbox Basics: Using display: flex to align my navigation links neatly across the top of my portfolio.
    
​🔗 3. Technical Mastery
​I now know the difference between an Element (the whole thing), a Tag (the label), and an Attribute (the extra settings like href or src).
