How CSS Works with HTML
CSS (Cascading Style Sheets) is used to style and visually format HTML content. HTML provides the structure of a web page, and CSS controls how that content looks — such as its layout, colors, fonts, spacing, and positioning.
Think of it Like This:
·
HTML is the frame
of the webpage.
·
CSS is the styling
and cosmetics that make it look nice.
🧠 How It Actually Works (Behind the Scenes)
1.
The browser loads your HTML file.
2.
It sees any CSS rules (inline, internal,
or external).
3.
It applies the CSS rules to matching HTML elements.
4.
CSS rules “cascade,” meaning the
most specific rule takes effect if there's a conflict.
Types of CSS
CSS (Cascading Style Sheets) has three
main types based on how it is applied to HTML documents:
1.
Inline CSS
- Applied directly to an HTML element using the style attribute.
- Scope:
Affects only that specific element.
- Usage:
Quick styling or overrides, but not recommended for maintainability.
2.
Internal CSS (Embedded CSS)
- Placed inside a <style> tag
within the <head> section of the HTML document.
- Scope:
Applies to the whole HTML document.
- Usage:
Useful for single-page websites or quick tests.
3.
External CSS
- Written in a separate .css
file and linked to the HTML
document using a <link> tag.
- Scope:
Applies styles across multiple HTML files.
- Usage:
Best practice for large and maintainable websites.
