Insert EPiServer page properties into CSS-files with EPiCssModifier

Have you ever wanted to replace hard wired image urls in your css files with images selected from EPiServer? That is, without using inline css in your templates.

Usually, your css may look something like:

image

You want to let the editors pick the image for the logo, right?

If you’re using PageTypeBuilder – which you should – then it’s only a matter of adding a property attribute to your page type class. Like so:

image

The CssFragment attribute in the property declaration means that you want to replace /ui/gfx/logo.png in all css-files with whatever value LogoImage contains.

What happens when you render the page is that the css links are modified slightly. This is your original css link:

image

Instead, it will render:

image

Note the appended query string to the css link.

Then a http handler will catch the request to the css-file and do a simple search and replace based on the query string parameters. The result will be a css that looks like this:

image

Prerequisites:

1. EPiServer CMS 6

2. PageTypeBuilder

To use:

1. Unzip, compile and drop the EPiCssModifier.dll in your /bin

2. Add this to the Web.config:

image

3. Voila! You’ve got yourself an inline-css free road to happiness.
