For example, consider the following line of text:

HTML [1]

HyperText Markup Language, commonly referred to as HTML, is the standard markup language used to create web pages. Along with CSS, and JavaScript, HTML is a cornerstone technology used to create web pages, as well as to create user interfaces for mobile and web applications. Web browsers can read HTML files and render them into visible or audible web pages.

HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language.[2]

For example, consider the following line of text:

My cat is very grumpy

If we wanted the text to stand by itself, we could specify that it is a paragraph by enclosing it in a paragraph element:

<p>My cat is very grumpy</p>

Note: Tags in HTML are case-insensitive. This means they can be written in uppercase or lowercase. For example, a <title> tag could be written as <title>, <TITLE>, <Title>, <TiTlE>, etc., and it will work. However, it is best practice to write all tags in lowercase for consistency, readability, and other reasons.

HTML (Hypertext Markup Language) elements historically were categorized as either "block-level" elements or "inline-level" elements. Since this is a presentational characteristic it is nowadays specified by CSS in the Flow Layout. Inline elements are those which only occupy the space bounded by the tags defining the element, instead of breaking the flow of the content.[4]
