📌 What are HTML Attributes?

HTML attributes give extra information about elements. They are added inside the start tag, usually as name/value pairs like name="value".

Attributes are like extra settings for HTML elements. They help define how an element behaves or appears. They are always written in the opening tag, like this: <p style="color:red">.
