In CSS, the tag selector is one of the most common and basic selectors. It allows developers to apply styles by selecting tags in HTML documents. Tag selectors use HTML tag names as selectors and can select all tags in the document.

The following are some common tag selectors:

1. Element Selector:

This is the most basic tag selector, using HTML tag names as a selector. For example, to select all paragraph elements, use the p selector:

   p {
     color: blue;
   }

This will set the color of all paragraph text to blue.

2. Universal Selector:

The wildcard selector uses * as the selector and can select all elements in the document. For example, to select all elements and set the font size to 14 pixels, you can use the wildcard selector:

   * {
     font-size: 14px;
   }

This will set the font size to 14 pixels for all elements in the document.

3. Class Selector:

The class selector uses the class name as the selector and can select elements with the same class name. To select all elements with the class name "highlight", you can use the class selector:

   .highlight {
     background-color: yellow;
   }

This will set the background color of all elements with the class name "highlight" to yellow.

4. ID Selector:

The ID selector uses the ID attribute of the element as a selector to select elements with a specific ID. To select elements with the ID "header", you can use the ID selector:

   #header {
     font-weight: bold;
   }

This will make the font of the element with the ID "header" bold.

5. Attribute Selector:

The attribute selector uses the attribute value of the element as a selector to select elements with specific attribute values. For example, to select all elements with the title attribute, you can use the attribute selector:

   [title] {
     color: red;
   }

This will set the text color of all elements with the title attribute to red.

These are some common tag selectors. By using them, developers can select and apply styles as needed, allowing for more flexible and personalized web design.
