Which are the most used languages in web development?

Question

If a person wishes to become a web developer then which are the most required languages that he/she must have a good hold on?

Answer 1

The three biggest web languages are HTML, CSS, and JavaScript.

HTML creates the structure.
CSS adds the style.
JavaScript defines the behavior.

For good measure, PHP is good for back-end stuff, too.

Answer 2

HTML,CSS, PHP, Asp.net, ruby on rails, java, JavaScript.

Answer 3

HTML for understanding the scheme of website.
CSS for giving a nice look for HTML
JavaScript for making website animations and dynamic edition of CSS. Also a must in single page application.
PHP for sturdy connection with databases.
And if you want your page to have balls, you put it in some framework, like RoR, Django, Spring or whatever...
