DOCTYPE

HTML Elements and Tags

A HTML Element may contain content (text, image, video etc), attributes and other elements in an HTML document.In the picture bellow, if you pick " <a href="/html/html-tutorials.php">Start Learning HTML</a>" for reference, then "<a href="/html/html-tutorials.php">" and "</a>" are HTML a tags. But " <a href="/html/html-tutorials.php">Start Learning HTML</a>" is an HTML element. So we can say that HTML Elements are composed of tags.

HTML Attributes

An HTML Attribute sets either style or layout or content related information for an HTML Element.

HTML Comments

An HTML Comment excludes a part of the code from being displayed in the browser.
