Okay lets learn how to build web applications. Before getting started first we should know what are the technologies we use.
  • We use HTML for interface design.
  • We use PHP for logic.
  • We use MYSQL for database. 
Okay lets start with HTML.

HTML is not a programming language but it is a markup language used to design web pages.The browser understands only HTML. So we should learn HTML in order to build a web app.What does a HTML page contains? It contains the basic elements like Heading,Menu bar,Form components like Text fields,Buttons,Check boxes,Radio Buttons,Drop Downs to take input from the user,Images,Audio video elements etc.Okay how all these are placed in a web page lets see, HTML is a fully tag based language it contains several set of tags each tag with specific operation.
So whatever the element needs to be placed in a webpage there will be a respective tag for that element that we need to know.The tags look like "<name of tag></name of tag>" every tag has opening and closing and all the tags in HTML are predefined and easy to remember.
Lets have a look at basic HTML document structure

<html>
<head>
<title>Structure</title>
</head>
<body>
<h1>Hello World</h1>
</body>
</html>
In the above code snippet we can see the root tag as html and the things that we want to display on the web page are placed in between the body tag. In this way a html page design goes.
