HTML tags have attributes. Attributes allow you to change different properties of the tag. They always go inside the start tag. For example:

<h1 style=”color: red”; > Hello World </h1> 

The attribute in the above example is called style. We are putting the style attribute inside a <h1> tag. The style attribute allows you to change the way a tag is styled. In this case, we are styling the <h1> tag to have the color red. There are many attributes that you can use in different tags.  Attributes always have follow the formula: attribute name = “value“

For example: (attribute name = width , value = 20px) leads to: width=”20px”
