HTML <h1>-<h6> Tags
The <h1> to <h6> elements are used to define six levels of HTML Headings, with <h1> being the highest (or most important) level and <h6> the least important one.
User agents may use heading information for automatically creating a content table for a document.
If you want to resize a text, it’s better not to use heading tags. You can use the CSS font-size property instead. It’s recommended not to skip heading levels ( <h1>, <h2>, <h3>, <h4>, <h5>, <h6>) and to use <h1> only once on a page.
Headline tags have SEO value as well. A search engine tries to find out two things about your page: what the page is about, and how good it is. One of the main things that search engines look at for determining a page content is the words inside heading tags.
When a page has a single piece of content, its main title must be in <h1> tag, the larger sections must be included in <h2> and so on. In this way, you can make your content more organized. You should remember that no one reads every word of content.
There are two types of pages with content: single content pages and index pages. On single content pages, the title of that piece of content must be in <h1> near the top of <body>. On an index page, the site title or the index name is usually put in <h1>. Then the titles of all the listed individual parts must have <h2>.
As the <h1> to <h6> tags are block-level elements, they always start on a new line and take up the full width available.
By default, <h1>-<h6> tags have the following properties: margin-left, margin-right, font-weight, display.
margin-left: 0;
margin-right: 0;
font-weight: bold;
display: block;Syntax
The <h1>-<h6> tags come in pairs, so the closing tag is required.
