Web application security - I strongly believe before learning to secure something, we should understand what we are securing. To secure web application we have to understand web application aka any application which we access via web browser.
What is browser - Almost every one uses in day to day life to check Facebook Gmail, Banking, E-shopping, Real estate and what not. Browser is very intelligent program which can understand HTML tags like <head>, <body>,<p> etc and parse it and present what you see on browser window.
I would recommend below resource for complete understanding and learning of HTML aka the web language.
Now we have HTML and Browser which are very basic for web site. Website with only HTML feature looks very plain and boring. To enhance its presentation and feature we use CSS(Cascading style sheet) and JavaScript.
CSS - used for styling of HTML where we can give color, font ,padding etc.
JavaScript - Is not scripting language from Java. Please read below link for better understanding of JavaScript.
Now you know what is HTML, CSS and JavaScript. I would encourage you to write a simple web page using HTML,CSS and JavaScript and open with your web browser.
We will see how to build a dynamic web page in part-2
