Selector
CSS selector classifies HTML elements according to their class, type, attribute, etc., then applies styles separately. You can select the elements that you want to style using the selector. Selectors enable you to customise the elements on a web page.
Here is an example of a CSS selector code,
h1 {
font-size: 22px;
}
Here, h1 is the selector, and font size 22px is the styling property and value. The selector chooses all the headings 1 on the page and sets their font size to 22px. The above-written code is an example of an Element selector, which selects elements based on the element name. There are various other types of selectors, such as;
Class selector that selects and styles elements based on the class attribute.
Id selector that uses the id attribute of an element.
Attribute selectors that choose elements based on an attribute or attribute value.
Pseudo-class selector selects elements based on their position or state.
Pseudo-element selector styles a specific part of an element.
