Clean Page Structure: Headings and Lists
by Anthony Stai
When HTML started, people put all sorts of things on their pages: there
was a tag to say which font you wanted your text to be in, a tag to say
you wanted it to be in the centre of the page, and so on. Now, though,
that way of writing pages is out-of-date and very inefficient compared
to keeping content and style separate using CSS.
What is CSS?
CSS stands for Cascading Style Sheets – it is basically a way
of saying once what you want your pages to look like, instead of having
to repeat it in HTML all the way through the document. In old style
HTML, for example, this kind of code was a relatively common sight:
<p><font face="Arial">Welcome to my
website!</font></p>
<p><font face="Arial">I hope you
enjoy your visit.</font></p>
Now, though, you can remove the font tags altogether, and just have
this:
<p>Welcome to my website!</p>
<p>I hope you enjoy your visit.</p>
At the top of your website, you put a style tag, like this:
<style>p { font-family: Arial,
}</style>
Now, instead of having to say again which font you're using with every
new paragraph, you've told the browser that you want every paragraph
you've got to be in Arial.
Headings and Lists.
Thanks to CSS, you can make documents that are more 'semantically
correct' – that is, they would make sense to a human reading
them, instead of having to be weighed down with lots of extra
presentation code. This has two great effects: it makes web pages
smaller (and so faster to download), and it makes them simpler.
On a modern web page, the only things you should ever need to include
apart from paragraphs of text are headings and lists. After all, web
pages are just text, graphics and navigation put together in a
particular order – there's no reason for things to be done as
messily as they often are.
You use headings for the title and subtitles of your page –
they're the HTML tags that begin with h. You might, for example, write
<h1>website
title</h1><h2>article
title</h2>.
Lists, on the other hand, can be used for pretty much anything else
that isn't paragraphs of text. Instead of just putting links one after
the other to make a navigation bar, for example, you should put them in
a list, using the ul and li tags. Not only is this easier for you to
read and add to, but it's also more compatible with non-graphical
browsers.
A typical list looks like this:
<ul><li>item
1</li><li>item
2</li></ul>
Bold, Italic, and Images.
Of course, in practice, you'll need a few more tags. CSS lacks any good
way of making individual words bold or italicised, so you can still use
your b and i tags. Images, of course, still need a tag of their own
too, although you might consider putting your images in a list if you
have more than one.
In theory, at least, that still means that it should be perfectly
possible to create a clean looking web page using only six tags: h, ul,
li, b, i and img. And, yes, it is very possible – if you can
stick to this attitude towards web pages, your page will be extremely
clean, quick to download and fast to display. If you've ever sat and
waited more than a few seconds for a page to load, you'll know how
important this is.
Custom Stylesheets.
One more advantage of this approach is that it lets your users view
your website however they want to. There are a surprising number of
users out there who are elderly or just want some consistency on the
web, and they have their own CSS stylesheets to add to pages to make
text bigger, for example, or make the layout simpler.
Once you've written your page cleanly, you can even offer visitors a
choice of stylesheets yourself – you can write more than one
and then offer an option to switch between them. This makes redesigning
your page much easier, if you ever need to, since you can simply swap
one set of CSS for another and even leave the old one available for any
visitors that prefer it.
