In HTML and CSS, an attribute selector is used to select any element with a specific attribute or value. This is a great way to style HTML elements by grouping them based on some specific features, and the feature selector will select elements with similar elements.
In CSS LifeStyle Example: We know that styling HTML elements with their tag names, class names, ID names, etc. This all will apply the changes to all tags or all classes or all ID names within the page. But if I have a situation where I want to apply styles to a tag name but only a few of them we just name their attribute in the indexing bracket. Therefore that it can only apply those changes to matching tag name and attribute name matching elements.
Here are 7 CSS Attribute Selector Syntax:
- [attribute]
- [attribute=value]
- [attribute~=value]
- [attribute|=value]
- [attribute^=value]
