Study Notes

CSS Basics

CSS is used to style an HTML document, describing how HTML elements should be displayed.
CSS is essential for defining styles for web pages, including design, layout, and variations in display for different devices and screen sizes.

CSS Syntax

A CSS selector points to the HTML element you want to style.
The declaration block contains one or more declarations separated by semicolons.
Each declaration includes a CSS property name and a value, separated by a colon.
Multiple CSS declarations are separated with semicolons, and declaration blocks are surrounded by curly braces.

CSS Selectors

CSS selectors are used to "find" (or select) the HTML elements you want to style.
The CSS element selector selects HTML elements based on the element name.
The CSS id selector uses the id attribute of an HTML element to select a specific element.
