hi
i have bulit a few sites in dreamweaver using CSS but have generally kept my CSS code specific to each document, in the script part of each document

i know that you can work off external style sheets but i just havent got around to working out how to do it.

now i am starting a new site i figure its a good time to work out how its done.

so could someone explain how i set this up, i want one style sheet that all my pages refer to,

i want to be able to ammend throughout design so it will update all the pages


Thanks

To reference a style sheet (in this case let's call it mystyles.css), you add a reference from within each page's HEAD tag.  Each page therefore must reference the external style sheet like this:

<head>
<title>The usual page's title here</title>
<link href="mystyles.css" rel="stylesheet" type="text/css">
</head>

You have to open up the style sheet and work directly in there.  I think Dreamweaver will let you edit the style from the Style menu toolbar when working with a web page, but it's easier to work directly in the style sheet file.
It's also safer to work directly in the css file.  Remember that by tweaking a style to look okay in one page, you could inadvertently mess up it's look in all the other page files!

so if i create a new layer, say a menu bar that i want to have the same style accross the whole website, i create the layer in the page say index.html how can i make sure that the related css is saved in this external CSS doc, do i have to export it (if so how?) or can i set it up to save the new layers CSS in the external page. Or do i need to create the CSS within the external doc and then import it in as directed above.

If i am missing the point completly, let me know.


thanks

If you go into code view you will see all the styles defined for your layer.  Depending on how the code is written it might look something like this -

<style type="text/css">
.myLayer {
  width: 150px;
  height: 100px;
  display: none;
  color: black;
  background-color: #eeeeff;
  z-index: 100;
}
.otherStyles {.....whatever...
}
</style>

You can see what the class name is in Dreamweaver in the properties panel (above in my example it is called .myLayer).
If you then take out all reference to myLayer, so the code looks like this:

<style type="text/css">
.otherStyles {.....whatever...
}
</style>

And then paste the bit you took out into the CSS file:

.myLayer {
  width: 150px;
  height: 100px;
  display: none;
  color: black;
  background-color: #eeeeff;
  z-index: 100;
}

Then when you reference the CSS file from the web page, the properties will be applied back to your layer element.  The class names will still be available in dreamweaver when you are editing your pages because as soon as it sees the reference to the CSS file, it reads in all the class names (.myLayer etc) and allows them to be assigned to elements within that page.
