In web development, the commonly used data selectors (element selectors) include the following:
ID selector : Use the # symbol followed by the ID name of the element. For example, to select the element with the ID "myElement", you can use #myElement.
Class selector: Use the . symbol followed by the class name of the element. For example, to select an element with the class name "myClass", you would use .myClass.
Element selector: Use the element name directly as the selector. For example, to select all
elements, you can use div.Attribute selector: Select elements with specific attributes. For example, to select elements with data-attribute attributes, you can use [data-attribute].
Pseudo-class selector: used to select a specific state or position of an element. For example, to select the first child element, you can use: first-child.
Descendant selector: Selects descendant elements of the specified element. For example, to select all
elements within the
element, you can use div p.Adjacent sibling selector: selects sibling elements adjacent to the specified element. For example, to select the
element immediately after the
element, you can use h2 p.
Wildcard selector: Use * to select all elements. For example, to select all elements on the page, you can use *.
These selectors can be used alone or in combination to select the required elements more precisely. In a CSS style sheet, these selectors can be used to select and apply styles to corresponding elements.
