The tag used to define the main heading in an HTML document is the

tag. This tag signifies the highest level of heading within the document structure. It generally represents the primary title or main topic of a page and is crucial for both SEO and accessibility purposes.

Using

contributes to the semantic structure of the HTML document, helping search engines and assistive technologies to understand the hierarchy and importance of the content. It provides context, indicating that this heading is the most significant in relation to the content that follows. In a well-structured document, there should typically be one

tag, with subsequent headings represented by

,

, and so on, to create a clear and organized content hierarchy.

Other tags like

serve as subheadings and have a lower level of significance than

. The tag is meant for the title of the document that appears in the browser tab and is not used for headings within the content. The <header> tag is used to wrap introductory content or navigational links but does not specifically define a heading itself.</p> <ins class="adsbygoogle" style="display:block; text-align:center;" data-ad-layout="in-article" data-ad-format="fluid" data-ad-client="ca-pub-5859049766823588" data-ad-slot="7513340117"></ins></div></div><div class="row justify-content-center button-selection"><div class="col-md-5 d-grid gap-2 mt-4 mb-3"><a class="btn btn-outline-dark" href="/multiplechoice"> <div class="mt-1 text-center">More Multiple Choice Questions</div></a></div></div></div></div></section><section><div class="bg-light"><div class="container content-space-2"><div class="w-md-75 w-lg-50 text-center mx-md-auto"><div class="row justify-content-lg-between" style="margin-left: 10px; margin-right: 10px;"><!-- Heading--><div class="mb-5"><span class="text-cap">Subscribe</span><h2>Get the latest from Examzify</h2></div><div class="input-card input-card-pill input-card-sm border mb-3"><div class="input-card-form"><label class="form-label visually-hidden" for="subscribeForm">Enter email</label><input class="form-control form-control-lg" id="email" type="text" placeholder="Enter email" aria-label="Enter email"></div><button class="btn btn-primary btn-lg rounded-pill" id="save-email" type="submit" disabled>Subscribe</button></div><p class="small">You can <a href="https://examzify.com/unsubscribe">unsubscribe </a>at any time.
