Answer 2

Hey there!

It is good that you realise that you require HTML, CSS and JavaScript.

Think of your website as a house.

Then HTML is the bricks and mortar that makes up your house (hence it is markup language not programming language).

Now that your house is made you need to do styling. So like the tiles and furniture of your house, CSS decorates and styles different elements of your website.

Now JavaScript is optional. Many websites are made using only HTML5 and CSS3.

JavaScript is used to make your website more interactive.

(If you want to see the difference between a website with JavaScript and without JavaScript then you can turn off JavaScript in your browser for a day.)

For a more professional website, JavaScript is necessary.

First learn how to make a website only using HTML5 and CSS3.

Then actually make a website. When you have made a website that you are proud of then learn JavaScript.

As is said : master the basics then move on to the advanced.

Answer 3

Neither stated the obvious. Web browsers only understand HTML, CSS, and JS so that is really your own choice to make a site. They did cover the reasons why you would want to use them together. HTML only sites are only good for displaying fixed pages of information with limited display choices.
