What Are Heading Tags?<\/h2><\/div>

In HTML, heading tags are used to organize the structure and hierarchy of your content. There are six levels of headings, from <h1><\/mark> to <h6><\/mark>, each showing a different level of importance. The smaller the number, the more important the heading \u2014 and the larger the text appears. <\/span>For example, <h1><\/mark> <\/span>is usually the main title, while <h6><\/mark><\/span>\u00a0is used for the smallest subheadings.<\/span><\/p>\n<\/div>

What Does <hn> Mean?<\/h3><\/div>

You might sometimes see people mention <hn> tags, but here\u2019s something important to know: isn\u2019t an actual HTML tag. The n simply stands for \u201cnumber,\u201d and it\u2019s a general way programmers refer to all heading tags \u2014 from <h1><\/mark> to <h6><\/mark>. In real HTML code, though, you need to use one of the specific tags: <h1><\/mark><\/span>, <h2><\/mark><\/span>, and so on, up to <h6><\/mark><\/span>. <\/span>Each one helps structure your content clearly and meaningfully.<\/span><\/p>\n<\/div>

The Role and Meaning of <h1><\/mark> to <h6><\/mark> Tags<\/h3><\/div>\n
\n\n\n\n\n\n\n\n
Tag<\/th>\nPurpose<\/th>\nFeatures<\/th>\n<\/tr>\n<\/thead>\n
<h1><\/strong><\/mark><\/td>\nMain title of the document<\/td>\nDisplayed the largest. Recommended to use only one per page.<\/td>\n<\/tr>\n
<h2><\/strong><\/mark><\/td>\nSection headings<\/td>\nSlightly smaller than <h1>, but still important. Great for main sections.<\/td>\n<\/tr>\n
<h3><\/strong><\/mark> to <\/strong><h6><\/strong><\/mark><\/td>\nSubheadings and details<\/td>\nThe larger the number, the smaller the text and the less important it becomes. Used for finer structure.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Heading tags from <h1><\/mark> to <h6><\/mark> play an important role in both the visual and structural organization of your webpage. Web browsers apply default styles to these tags, making the hierarchy clear at a glance \u2014 with <h1><\/mark><\/span>\u00a0appearing largest and most prominent, and <h6><\/mark><\/span>\u00a0the smallest. <\/span>But their job isn’t just visual. <\/span>Screen readers also use these headings to help users navigate the content logically, which is especially important for accessibility. <\/span>And here’s a bonus: including relevant keywords in your headings can improve your <\/span>SEO (Search Engine Optimization)<\/strong>, helping your content show up more easily in search results.<\/span><\/p>\n<\/div>
