I have seen in videos, that people get html template by typing "html:5" or something like that (btw, they're not using notepad++). Is this possible in notepad++? Thanks.
A little late, but what you're looking for is called Zen Coding.
The Zen Coding project hosted on Google has a plugin for NotePad++ that should do exactly what you need.
For example, entering something like:
html>head+body>div#content>ul.nav>li*5
Followed by Ctrl + E, expands into:
<html>
<head></head>
<body>
<div id="content">
<ul class="nav">
<li></li>
<li></li>
<li></li>
<li></li>
<li></li>
</ul>
</div>
</body>
</html>
