CSS selectors | #css #shorts #coding

A CSS selector is a pattern or rule used to target and apply styles to specific elements in an HTML document. Selectors are an essential part of CSS because they define which elements the style rules will affect.

Types of CSS Selectors:
1. Universal Selector (*):
Targets all elements on a webpage.
• Useful for applying global styles like resetting margins or padding.
2. Type Selector:
Targets elements by their HTML tag name (e.g., div, h1, p).
• Example: Apply styles to all p tags in a document.
3. Class Selector (.classname):
Targets elements that have a specific class attribute.
• Classes can be reused across multiple elements, making them ideal for shared styles.
4. ID Selector (#idname):
Targets a single, unique element with a specific id attribute.
• IDs are unique and typically used for individual, specific styles.
5. Attribute Selector:
Targets elements based on the presence or value of their attributes (e.g., input[type="text"]).
• Commonly used for forms or elements with specific attributes.
6. Group Selector (selector1, selector2):
Combines multiple selectors, applying the same styles to different elements.
• Example: Style both h1 and p tags simultaneously.
7. Descendant Selector (ancestor descendant):
Targets elements nested inside a specific parent element.
• Example: Apply styles to span tags only inside a div .
8. Child Selector (parent - child):
Targets the direct children of a specific parent element.
• Useful for precise targeting in nested structures.
9. Sibling Selectors (element1 + element2, element1 ~ element2):
Targets elements that are adjacent or share the same parent in the DOM hierarchy.
10. Pseudo-Selectors:
• Pseudo-classes (:hover, :focus, :nth-child()): Target elements in specific states or positions.
• Pseudo-elements (::before, ::after): Target parts of an element, like adding content or styling a specific section.

Importance of CSS Selectors:

Selectors are fundamental to CSS because they allow you to pinpoint exactly which elements you want to style, enabling efficient and precise design control. By combining different selectors, you can create complex styles for modern web designs.
