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.

CSS Text and Border Colors

You can set the color of text using the color property.
You can set the color of borders using the border-color property.

CSS Color Values

Colors can be specified using color names, RGB values, HEX values, HSL values, RGBA values, and HSLA values.
RGB color values represent RED, GREEN, and BLUE light sources.
RGBA color values are an extension of RGB color values with an alpha channel, which specifies the opacity for a color.

CSS Backgrounds

The CSS background properties are used to add background effects for elements.
The background-color property specifies the background color of an element.

CSS Cascading Order

When there is more than one style specified for an HTML element, the styles will "cascade" into a new "virtual" style sheet by the following rules:
- Inline style (inside an HTML element)
- External and internal style sheets (in the head section)
- Browser default
Inline style has the highest priority and will override external and internal styles and browser defaults.

CSS Comments

Comments are used to explain the code and may help when you edit the source code at a later date.
Comments are ignored by browsers.
A CSS comment is placed inside the `
