Moving an internal style sheet to an external style sheet

Video: Moving an internal style sheet to an external style sheet

In the previous movie we created some styles for our page using Page Properties. We came in here and we changed Some things under Appearance, Links, and Headings. And I showed you that if you went over to the code view, you could see that the styles that we created are now embedded into this particular document, meaning that they apply only to this page and cannot be applied to other pages. But, if you spent all this time creating a look for your page and you're pretty happy with it, you don't have to open up all of your other pages, like for instance About Us, and open up Page Properties, and go through the whole process over and over again.

Moving an internal style sheet to an external style sheet

In the previous movie we created some styles for our page using Page Properties. We came in here and we changed Some things under Appearance, Links, and Headings. And I showed you that if you went over to the code view, you could see that the styles that we created are now embedded into this particular document, meaning that they apply only to this page and cannot be applied to other pages. But, if you spent all this time creating a look for your page and you're pretty happy with it, you don't have to open up all of your other pages, like for instance About Us, and open up Page Properties, and go through the whole process over and over again.

It would be much better to be able to take those styles and apply them to another page. And, another advantage to that would be, if you change your mind, and you don't like the background color, or something that, you can just change your external style sheet, and then all the pages attached to that style sheet will then change. Let's take a look at how this works. Now, if you're familiar with earlier versions of {italic}Dreamweaver,{plain} you used to be able to export your style sheets by going to the File menu, and choosing Export > Style Sheets. But, notice that option is not available here anymore. This ability has changed a little bit in {italic}Dreamweaver{plain} {italic}CS3,{plain} and I think it's a change for the better, because it's a little less convoluted than it used to be.

Previously, you export your styles, save a style sheet, but the original styles from this document would still remain in here. You'd have to come in here and delete them, and reattach this page to that external style sheet. This new method cuts out all those extra steps. What we're going to do is move our styles into an external style sheet that we're going to create, and then this page will automatically be linked to that style sheet. To do this, we need to go to our CSS styles panel, and make sure All is selected, and we'll talk more about this panel in an upcoming movie. But what you can see here are all the styles that we've created listed right here.

So, what we're going to do is click the very first style, scroll down, hold down shift, and click very last style to select all of those rules. Now, I'm going to right-click, or Ctrl + click, on those styles, and choose Move CSS Rules. This opens the Move To External Style Sheet dialog box, and I have the option of adding this to an existing style sheet, which I can browse for. Or, in this case, I'm going to create a new style sheet since I don't haven't any existing ones right now. I'll click on OK. I like to save these inside my assets folder, so let's go in there.

And, I'm just going to call this styles.css. We'll click save. Now, it doesn't look like anything has changed on this page, but I look inside my assets folder, sure enough, there is my styles document, so I do now have an external CSS document. You can see that {italic}Dreamweaver{plain} has already opened it up. All it is, again, is just a list of all of my CSS rules. But, notice on the About Tea page nothing really appears to have changed, even though I moved those styles. Let me go at the code. Notice that that big style block is now completely gone. I see those styles here anymore. All I have are my empty style tags.

But, what I do have in addition now is this line right here, which is a link to assets/styles.css, the external style sheet I just created, and we're linking to that style sheet. So, basically what this line is telling this page to do, is when you open up, look for the styles.css file, and do what it says. That's exactly what's going on here. We've removed all that extra code that was on this page. All it says is, look for that styles document, which is this, and it's just going to follow all of these rules. Over here in our Styles panel you can see where -- there's the styles.css file we're linked to. Now, we still have this style, which is in reference to these empty style tags here. So, if I don't need those anymore I can actually come in here and click the Trash icon with it selected. You can see it remove those empty style tags from here.

Not really necessary, but if you just want to clean up your code a little bit, you can do that. So basically, that was one step. I selected my styles, I moved them to an external style sheet, and {italic}Dreamweaver{plain} automatically linked my current document to that external style sheet. And now it's a simple matter of determining which other documents in my site I also want to link to that style sheet. Let's open up the file aboutus.html. Now let's open up brewingtea.html. These pages look a lot like the About Tea page looked before we applied our styles to it. But, instead of a having to open up Page Properties and apply our styles all over again, all you need to do is link to my external style sheet. We do this by coming over here to Styles panel, clicking this little Attach Style Sheet button. It looks like a little chain-link icon there. This allows us to browse for the style that we want to link to. I'm going to Browse, look inside my site folder, go to assets, and there it is, styles.css.

I'll click Choose. I just want to make sure that the link button is selected for Add as. We have a choice of Link or Import. Now, the import option uses a different syntax for linking to your external style sheets, and it's not supported by older browsers. It is a handy way to hide CSS code that older browsers don't support, but this Media option let's you specify the style sheet for a specific type of media. So, if you have an older browser, or different type of device, you can apply that. We're going to talk more about that in the chapter on designing for devices. In this case, we're going to make sure that we have links selected. All I did was select my style sheet, make sure Link was selected. I'm going to click on OK. And you can see right away, it's taken on the properties of that style sheet. You can see now that the styles.css is listed here is the CSS panel.

Let's do the same thing for Brewing Tea. Again, we're going to come in here, notice (no styles defined), we'll link to a styles.css. Another nice feature is that {italic}Dreamweaver{plain} remembers the last style sheet you linked to so you don't have to go browsing for it again. All you have to do is click on OK, and there it is. So, just like that my pages now all match. I'll just go through here and save all these things so I don't mess them up accidentally. So, you can see it's very easy once you have that external style sheet, to quickly change the appearance of several different pages just by attaching them to that style sheet.

and it's very easy to make changes that style sheet, to change all the pages. For instance, if I come to anyone of these pages, open up the Styles are here, and let's select the body tag, and maybe I decide I want to back ground to be white. Notice the change to white here, a change to white here, and a change to white here. Notice there's no asterisk next to any of these file names. The only item that has an asterisk next to it now is the Styles file, because we only changed the actual style sheet. We didn't change any of the other pages here. If I change my mind, and I want to go back, I can actually just close this without saving my changes.

And you can see that my three pages here default back to the original specifications in that style sheet. So that's how you move styles from an internal style sheet and turn it into an external style sheet. My CSS file again. I'm just going to go ahead and close brewingtea and aboutus.html. And I'll leave abouttea open for the next exercise.
