CSS selectors

Created By: chatGPT

In CSS, selectors are patterns used to select elements you want to style. There are several types of selectors, each serving different purposes. Here's a breakdown:

Type Selector selects all elements of a given type. For example, to style all

elements:

p {
    color: blue;
    font-size: 16px;
}

Class Selector selects all elements with a specific class. Prefix the class name with a dot (.):

.my-class {
    background-color: yellow;
    padding: 10px;
}

ID Selector selects an element with a specific ID. Prefix the ID with a hash (#):

#my-id {
    border: 1px solid black;
    margin: 20px;
}

Attribute Selector selects elements based on an attribute or attribute value. For instance, to style all elements of type text:

input[type='text'] {
    border-radius: 5px;
    padding: 8px;
}

Descendant Selector selects elements that are inside another element. For example, to style all elements inside a

div span {
    color: red;
}

Child Selector selects elements that are direct children of another element, using the > operator:

ul > li {
    list-style-type: none;
}

Pseudo-classes allow you to select elements based on their state. For instance, to style a link when hovered:

a:hover {
    text-decoration: underline;
}

Pseudo-elements allow you to style a specific part of an element. For example, to style the first line of a paragraph:

p::first-line {
    font-weight: bold;
}

Understanding these selectors is essential for effective CSS design. By combining different selectors, you can create powerful and flexible styles for your HTML.
