There are 6 levels of headings in HTML. H1, H2, H3, H4, H5, H6 are the 6 levels where H6 is the highest and H1 is the lowest. These tags are used for writing the title and the subtitles on the web pages. The information in between these tags is printed in bold and the size depends on the numbering. The search engine takes the help of the headings to understand and index the structure of web pages.
A title or a subtitle that you want to display on the webpage can be defined as an HTML heading or HTML h tag.
The style attribute can be used to adjust the default size of HTML headers.
In an HTML page, the "hr" tag, which stands for the horizontal rule, is used to establish a theme break. It's primarily used to divide content.
The HTML head element serves as a metadata container. Metadata is information about an HTML document that isn't visible. Headings have nothing to do with the head element. Instead, between the "HTML" tag and the "body" tag is the head element.
