The Text Tag Group is a group of tags that are used to create well-formatted text documents.
Text tags include <h1>-<h6>, <p>, <br>, <span>, <b>, <sup>, and others.
Originally, HTML was designed as a text formatting language for scientific documents.
This allowed formatted text documents to be easily shared electronically.
With this legacy, HTML has a rich assortment of tags that help with text formatting.
Here is a list of text tags that are available to format text documents.
Together, they allow you to create comprehensive HTML text documents.
| Element | Description |
|---|---|
| <h1>-<h6> | Defines text headings in 6 different sizes |
| <p> | Creates a paragraph |
| <span> | Container for one or more inline text elements |
| <br> | Creates a line break |
| <sup> | Specifies superscript text |
| <sub> | Specifies subscripted text |
| <u> | Specifies underlined text |
| <i> | Specifies italic text |
| <b> | Specifies bold text |
| <em> | Marks text that needs emphasis |
| <strong> | Indicates text that is important or with high urgency |
| <del> | Defines deleted text |
| <ins> | Defines inserted text |
| <ruby> | Represents a small annotation with pronunciation of text |
| <kbd> | Specifies keyboard input, such as, CTRL or ALT |
| <wbr> | Specifies a preferred word-break location for long words |
Tip: More recently, text formatting and styling has shifted from HTML to CSS. Rather than using <b>, <i>, <u>, <em>, or <strong>, web developers prefer CSS which gives them more control.
A scientific document formatted with different text tags.
In chemistry, alcohol is an organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic beverages.
An important class of alcohols, of which methanol and ethanol are the simplest members, includes all compounds for which the general formula is CnH2n+1OH. Simple monoalcohols include primary (RCH2OH), secondary (R2CHOH) and tertiary (R3COH) alcohols.

<h3>Introduction</h3>

In chemistry, <b>alcohol</b> is an organic compound that
carries at least one <i>hydroxyl functional group</i>
(−OH) bound to a saturated carbon atom.
The term alcohol originally referred to the primary
alcohol ethanol (<i>ethyl alcohol</i>), which is used as
a drug and is the main alcohol present in alcoholic beverages.

(R<sub>3</sub>COH) alcohols.

<h2> and <h3> tags are headers that specify the document hierarchy.
HTML began life in CERN, the European Lab for Particle Physics in Geneva, Switzerland.
Physicists from all over the world had a need to share their scientific ideas and documents.
In 1989 Tim Berners-Lee invents HTML with these 18 tags:
<title><nextid><a><isindex><plaintext><listing><p><h1> - <h6><address><hp1> - <hp2><dl><dt><dd><ul><ol><li><dir>In case you're interested this is the original HTML proposal.
Note: It's clear that HTML has evolved; today more than half of the original 18 tags are obsolete.
