2. ID Selector: Use the ID attribute of the element to select HTML elements. For example, to select the element with ID "myElement" you can use $("#myElement").
3. Class Selector: Use the element's class name to select HTML elements. For example, to select an element with the class name "myClass" you can use $(".myClass").
4. Attribute Selector: Use the element's attributes to select HTML elements. For example, to select all elements with the "data-id" attribute you can use $("[data-id]").
5. Child Selector: Selects the direct child elements of the specified element. For example, to select all paragraph elements under the element with ID "myElement" you can use $("#myElement > p").
6. Descendant Selector: Selects the descendant elements of the specified element. For example, to select all paragraph elements under the element with ID "myElement" you can use $("#myElement p").
7. Sibling Selector: Select adjacent sibling elements of the specified element. For example, to select all sibling elements following the element with ID "myElement" you can use $("#myElement p").
