What is HTML?
HTML is a static language for text formatting for web pages use. All web pages on the web consists of HTML which is sent to the browser for rendering. Browser interpret the HTML and convert it into colors, fonts and design. HTML is the abbreviation of Hyper Text Markup Language which means a language for writing text contents with non text contents i.e. list, table, alignment etc…
HTML mainly consists from TAGS with some contents inside. i.e. <p>Hello World</p> this tells the browser that there is a paragraph with the sentence “Hello World” inside. Similarly <img src=”http://path/to” /> tells the browser to display an image located at the url http://path/to
HTML has many versions starting from HTML 4.0 which issued at late 1997 until the most recent HTML5.
HTML5 has incorporated many new TAGS and supports a wide range of contents other than images like video and audio.
What is CSS?
CSS is the abbreviation of “Cascaded Style Sheets” and it is a coding method to let the browser knows the design of the HTML contents rendered. The word design here means colors, alignment, spacing, borders, backgrounds, font, width, height, etc… Because there is no code running here, CSS is considered a static language “Not a programming language”.
There are three different ways to embed a style sheet it can be either embedded into the tag, in a separate block in the page or in a separate file.
The syntax for embedding into a tag is as following:-
<p style="color:red;">Some red text</p>
While the syntax for writing the style sheet into a separate block is just writing all styling enclosed into a style tag.
Last way of writing style sheets is by writing the styles into a separate file with the extension .css then adding the following tag into the head section.
<link rel="stylesheet" type="text/css" href="path/to.css" />
What is PHP?
What is MySQL?
While you can use files to store your data but it is not good idea especially if you want functionalities like user search or reordering. Here a DBMS (Database Management Systems) comes into hand. With MySQL which is a freely distributed open source DBMS you can insert, update or query data using the standard SQL statements.
