(Semantic) elements to structure a page into sections are

<article>
<header>
<main>
<nav>
<footer>

Some elements are so-called void elements: area, base, br, col, embed, hr, img, input, link, meta, source, track, wbr.

Replaced elements

The CSS specification makes mention of a replaced element. The rendering of replaced elements is not dictated by the CSS model. A typical example for a replaced element are the <img> or <video> element.

The object-fit CSS property defines how the content of a replaced element should be resized to fit its container.

No self closing tags in HTML

Unlike XML, XHTML or SVG, HTML does not require self closing tags such as <br/>

If the parser encounters a self closing tag, the slash is ignored.

Void elements

A void element cannot have any child nodes.

Unlike SVG or MathML, a void element must not have any end tag, so <meta …></meta> would be wrong.
