Why HTML5, CSS3, PHP and Javascript?

While working online, one comes across many concepts like HTML5, CSS3, PHP and Javascript. These are important to understand atleast with a 30,000 feet view and we should be aware of what each one does and where do we use them.

HTML5 is a markup language for structuring and presenting content for the World Wide Web. It allows sites to be more dynamic and interactive so that they can be indexed better and can communicate with other websites via APIs. It is the latest version of Hyper Text Markup Language. To summarize, HTML5 is used to define the content of web pages.

CSS is a style sheet language used to describe the presentation semantics (the look and formatting) of a document written in a markup language. To summarize, CSS is used to specify the layout of web pages.

Javascript is a scripting language. It is mainly used to access and manipulate the elements created using a markup language. To summarize, Javascript is used to program the behavior of web pages.

PHP is a powerful yet simple open-source scripting language that is widely used. It is an acronym for “PHP: Hypertext Preprocessor”. It is used in WordPress and in Facebook. PHP is a server scripting language, and a powerful tool for making dynamic and interactive Web pages.

PHP is quite incredible and can do quite a few things like:

  1. Generate dynamic page content
  2. Create, open, read, write, delete, and close files on the server
  3. Collect form data
  4. Send and receive cookies
  5. Add, delete, modify data in a database
  6. Control user-access
  7. Encrypt data

Overall, learning HTML5, PHP, CSS and Javascript should be good enough to make any changes to your code even if you haven’t written the code yourself. Changes that you may need to do may include code for any advertising networks that you subscribe to should you decide to monetize your blogs or slight modifications to enhance the security of your blog or maybe even inclusion of videos or audios.
