In what order it is appropriate to learn HTML, CSS, HTML DOM and javascript?

You should start from HTML. That is the basis for all the others. CSS is a language that will help you create the design of your website without using tables.(it has many other advantages) But, even if you don't know CSS you can still build websites.

Without HTML you can't do anything with CSS. Javascript is a language to add bits and pieces to the HTML code. Adding some extra features is nice but without having a basic page you don't need them at all.

I'm actually not sure about HTML DOM. (but whatever it is it can't be more important than HTML to start with). If you want to learn HTML check out my hub:http://hubpages.com/hub/How-to-Build-a-Website-HTMI also have another hum related with that one that is the introduction to build a website that might also be useful to you.

Hope this helps.

They are so closely related that you should probably learn them at the same time. HTML and CSS work hand in hand. I programmed for years with HTML, but then I discovered CSS!

Oh man, what a difference! It's SOOOO much easier using CSS in your HTML and using the tags for formating. Learn CSS WHILE you are learning HTML and you won't be sorry.

HTML is the basic markup language use to create web pages. CSS use to make stylish web pages. So it's better to learn basic and move on.So I recommend you to learn 01.

HTML 02. CSS03. Javascript04.

DOM.

I really need to know about. So answer if you know about it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
