Heading tag is HTML is a term used to define the webpage headings by a specific code with “n” being a number between 1 and 6, and determines which position a heading has in the hierarchy of the heading structure.
What are Heading Tags?
Heading tags have a particularly important function within an HTML structure. An HTML file can be understood as a combination of nodes, whereby the heading tag is the starting point from which other nodes, i.e. content or other headings, branch out. An HTML file should therefore just have one H1 heading, even through it is in theory possible to use multiple H1 tags. Lower-order headers can be used as often as desired, but should be chosen in such a way that there is an understandable hierarchy. Heading tags are used to display text, and the formatting of headings should be specified in the CSS files to separate formatting and content.
Why are Heading Tags Important?
Heading tags provide structure to an HTML file, and specify what type of data the browser should display. How the data is to be displayed, for example font size or colors should be determined in the CSS files. The use of heading tags is a must if you want to display text content. Each HTML file should have only one start node (h1 tag) if it is to be valid. The W3C Validator can be used to check the validity of an HTML document.
A well-structured HTML file offers the following advantages for users and search engines.
1) Headings can be interpreted by browsers, which may not be able to recognize or display the custom style sheets.
2) Screen readers and magnifiers refer to headers (accessibility and display on mobile devices).
3) A clear structure is given: The user receives instructions concerning the content and can decide which paragraphs are of interest to them.
4) Search Engines obtain valid source code and other signals in the form of relevant keywords from headings that summarize the content.
5) Changes can easily be made to all headers: Only a small change to the CSS file is required and all headings receive formatting instructions.
