WHAT IS HTML?
HyperText Markup Language (HTML) is the set of markup symbols or codes inserted into a file intended for display on the Internet. The markup tells web browsers how to display a web page's words and images.
BASIC HTML TAGS:
<h1> which describes a top-level heading.
<h2> which describes a second-level heading.
<p> which describes a paragraph.
<table> which describes tabular data.
<ol> which describes an ordered list of information.
<ul> which describes an unordered list of information.
HTML VERSIONS:
HTML 1.0 -- released in 1992 -- had very limited capability and around 20 elements.
HTML 2.0 -- released in 1995 -- began to incorporate elements relating to math functions.
HTML 3.2 -- released in 1996 -- dropped the math function initiative altogether and fixed overlap between various proprietary extensions.
HTML 4.0 -- released in 1997 -- offered three variations that differed in the number of deprecated elements that were allowed.
HTML 4.01 -- released in 1999 -- largely the same as 4.0.
HTML 5 -- released in 2014 -- came after a long break in updates because the organization that developed it -- W3C -- was focusing on another, a parallel language called XHTML.
HTML 5.1 -- released in 2016 -- aimed to more easily accommodate various types of media embedding with new tags.
HTML 5.2 -- released in 2017 -- aimed to be equally understandable by humans and computers.
HTML 5.3 -- yet to be released -- W3C is collaborating with WHATWG on a new version. The collaboration began in 2019.
How Are HTML, CSS, and Javascript Related:
HTML is used to add text elements and create the structure of content. However, it is not enough to build a professional and fully responsive website. So, HTML needs the help of Cascading Style Sheets (CSS) and JavaScript to create the vast majority of website content.
CSS is responsible for stylings such as background, colors, layouts, spacing, and animations. On the other hand, JavaScript adds dynamic functionality such as sliders, pop-ups, and photo galleries. These three languages are the fundamentals of front-end development.
The most basic of HTML conventions is the inclusion of a document type declaration at the beginning of the text file. This always comes first in the document, because it is the piece that affirmatively informs a computer that this is an HTML file. The document header typically looks like this: <!DOCTYPE html>. It should always be written that way, without any content inside it or breaking it up. Any content that comes before this declaration will not be recognized as HTML by a computer.
