H2 heading tag It defines the second-level headings on your webpage. Like an H1 tag, an H2 tag also appears larger than the rest of your main body text. However, H2 tags are always slightly smaller than your H1 tag, so that it does not compete with your main heading. Keep in mind that heading tags don't stop at H2.

To make the header take up the whole top of the screen in HTML, you can use CSS to set the margin and padding of the body and header elements to 0, and then set the height of the header to 100vh. This will ensure that the header takes up the entire viewport height.

The H3 element defines a level-three heading. This heading is more important than an H4 but less important than an H2. The deprecated ALIGN attribute suggests the horizontal alignment for the heading on visual browsers. Possible values are left, right, center, and justify.
