Ok, cool thanks.
I have heard of Dreamweaver but we are not allowed to use it. I guess we are meant to learn the hard way by typing everything in at first.
Have a look at
these editors. Some of them are quite decent, actually--Notepad++ is a favourite of many of my colleagues. Me, I prefer Sublime Text for general-purpose text editing, but it (now in version 3) costs money. For $70, you get a really good editor, though, and I believe several HTML plugins are available.
Dreamweaver will hide the tags but the above text editors will all display them. They will help you avoid syntax mistakes like missing end tags, and they will suggest elements and attributes depending on context.
Also, the W3C provides an HTML editor called Amaya. You might want to have a look at
