Overriding a CSS style

Video: Overriding a CSS style

Having a style sheet attached to multiple pages is powerful but that doesn't mean that every page has to look the same. You can add CSS to individual pages that will then override any CSS rules in an attached style sheet. So currently, I have in this site, these multiple pages and from page to page, the layouts are exactly the same, the images are exactly the same. And really I want to add a little more flavor from page to page. In particular, what I want to do is I want to change the background from page to page.

Overriding a CSS style

Having a style sheet attached to multiple pages is powerful but that doesn't mean that every page has to look the same. You can add CSS to individual pages that will then override any CSS rules in an attached style sheet. So currently, I have in this site, these multiple pages and from page to page, the layouts are exactly the same, the images are exactly the same. And really I want to add a little more flavor from page to page. In particular, what I want to do is I want to change the background from page to page.

For this about page, for instance, I can change the background quite easily by clicking Page Properties. So, in the Appearance (CSS) category, all I need to do is change my background image. So, I'm going to click Browse and I'm going to locate this BkgdAbout.jpg. That's in the images folder. I'm going to click Choose, select OK, sure enough the background changes.

So, if I get to expand this CSS Styles panel a little bit, notice how it's applied this new, sort of local style to this page. In fact, it's a body style and this is the image I just added. So this image actually overrides this image in the body rule established in the janedoe.css.

So, since this is an attached style sheet, it will apply that style but if there is anything local attached solely on this page, this style will take precedence over anything in an attached style sheet. So that's what does the trick. It applies this particular image in the background, and it looks pretty darn and good. In fact, I'll go ahead and save this page and I'll preview it in a browser. Sure enough, there it is, there is the image, and it's looking pretty good.

But still, it keeps the consistency of the rest of the elements. So it's still sort of part of the same site, but looks different enough. So, I would want to do that across the board. So, for the portfolio page, I want to do the same thing. Again it's overriding this background image just by clicking Page Properties and under the Appearance category CSS, I want to change the background image, and in the images folder, there is the BkgdPortfolio. Click Choose, select OK, and again, it does the same thing.

It applies this style, and if I can do one more thing here, I'm going to right-click or Control-click and I'm going to go to Code. By doing that it will go to that CSS style just to show you that it exists on this page. So, this style overrides anything that might be in a style sheet that's attached. Again, I'm going to click on Design view, there is my page. It's looking really good. I'll save this page.

Let me go to the contact page and the same thing here, I'm going to click Page Properties > Appearance (CSS) section > Background image, I'm going to browse to the BkgdContact.jpg. I'll choose that, select OK, puts that image back there, and again it's sort of what you call a local style. And then I'll go ahead and save this page. So, let's check this out in action.

If I go back to the index.html and I preview this in a browser, we can see that here is my home page, I can go to the about page. Again, we are consistent with the design, with the layout. It's just the image in the background that changes. So again, my portfolio page, and then the contact page. Again, I was able to override any sort of attached style sheet rule, and really it gives me the flexibility to add more personality and customization per page while keeping consistent with the entire site.
