HTML (Hypertext Markup Language)
HTML is the must learn for web development. It is used to make web pages.
CSS (Cascading Style Sheets)
CSS describes the style of a Web page, as well as how the elements should be displayed on it. Here's an example of a Web page with and without CSS:
Django is a web development tool that runs on Python and HTML/CSS. You must have a basic knowledge of Python to use Django. Instagram, Spotify, Youtube, Mozilla, Nasa’s website, Prezi, National Geographic & more use Django to build their websites. Django is more powerful than Flask and has more built-in features, but is a bit more complicated to learn.
Flask is a web development tool that runs on Python and HTML/CSS. It is less powerful than Django and is more difficult to use if you need to have a user authentication system or a database on your website. However, it is less complicated than Django for simpler tasks.
PHP is a programming language that is made for web development. It is used by 80% of the web. Yahoo, Facebook, Wikipedia, and more use PHP to build their websites. However, like any other web development tool, you must be able to code in HTML/CSS in order to use PHP.
