? About CSS (Cascading Style Sheets)
CSS is a stylesheet language used to control the appearance and layout of HTML documents on the web. It describes how elements should be displayed — including colors, fonts, spacing, positioning, and more.
What is CSS?
Cascading Style Sheets (CSS): The "cascading" part means styles can be layered, and the most specific or important style wins.
Separates content (HTML) from presentation (CSS).
Enables responsive designs that adapt to different screen sizes.
Works alongside HTML and JavaScript to build web pages.
How CSS Works
Selectors target HTML elements.
Properties define what aspect to style (color, size, margin...).
Values specify the exact style (e.g.,
red,20px).
Example:
p { color: blue; font-size: 16px; margin-bottom: 1em;}This styles all <p> elements with blue text, font size 16 pixels, and spacing below.
