h2 element

If you don't know what an element is or how you must use it, I recommend you read the "HTML tags and attributes" tutorial that you can find in the HTML tutorials section.

Description

The h2 element represents a level 2 heading. Headings (from h1 to h6) are titles that define implied sections in the document and arrange its contents in a hierarchical structure.

When headings are combined with the section element the sections of a document are no longer implied but exactly defined. In such cases, the heading of a section should lead all other elements.

Examples

The next example shows a document with some headings creating a hierachical structure. The results, displayed under the code, can provide a clearer view of this fact and make it easy to understand tath "Works" and "Musical style" are subtitles (and subsections) for "Johann Sebastian Bach", and "Organ works", "Orchestral works" and "Vocal works" are subtitles of "Works".

<h1>Johann Sebastian Bach</h1>
<p>Johann Sebastian Bach was a german composer and musician of the Baroque period. He was born on March 31st, 1685...</p>

In our second example, we'll make use of the section element toghether with exactly the same structure used before. The semantic in the structure of this new document matches exactly the one in the previous example.

<body>
  <h1>Johann Sebastian Bach</h1>
  <p>Johann Sebastian Bach was a german composer and musician of the Baroque period. He was born on March 31st, 1685...</p>
  <section>

</body>

Now, the sections are explicitly and unambiguosly defined, including the body section of the document.

Note that, in this outline, the headings of each section could be represented by an h1 heading, despite the level of the heading in the parent section. This is because the level one heading at the begining of a section element represents the main title in the scope of that particular section and not in the entire document.

Althoug the use of h1 headings as titles for sections is entirely possible and standard conformant, authors should be aware that, by default, legacy browsers will render all h1 elements with the same style.

Attributes

Specific attributes

align

The horizontal alignment of the heading. There are four possible values (case-insensitive):

  • left: heading is aligned to the left margin.
  • center: heading is centered.
  • right: heading is aligned to the right margin.
  • justify: heading is justified or aligned to both margins.

The use of this attribute has become obsolete in HTML5 and, therefore, its use is no longer valid. Authors should replace it with style sheets declarations.

Example

<h2 align="center">The truth is out there</h2>
