Web sites can contain hundreds of pages,
even thousands. You have spent your time making a look and brand
for your web site, using different font sizes, colours, margins
etc all within each web page.
Later on you decide that you want to change the background
colour of the website, and then realise that you will have to
edit every single web page and change the background color in
the body tag.......
This is
where stylesheets come into play, by simply putting all the web
page formatting into a single file and then called upon by each
web page, you are able to make changes to your web sites layout
in just a few seconds!
To do
this, include the following piece of code inside your
tags.
This tells the browser that
to display the page with the proper formatting to use the file
called stylesheet.css. So any changes you want to make to the
page, you simply edit the stylesheet.css file, save and then
voila! All your pages using that stylesheet have now changed.
