Microsoft highly recommends no modification of the application.master is is responsible for the look and feel of the what I call “admin” pages. This includes Site Settings and just about every page linked from there. And I stress this to our PMs and BD personnel when they talk to clients regarding branding their sites.
However, you can “brand” these pages using just CSS. Beware though if you are like me and decimate the default.master and craft it to your needs. Especially if you move all of those seemingly useless contentplaceholders (like PlaceHolderTitleLeftBorder, PlaceHolderTitleRightMargin, PlaceHolderBodyLeftBorder, etc.) to your hidden panel. You’ll most likely be missing some of the classes used to style the application.master and will need to accommodate for these.
Case in point
See the area in the red box in the picture below? This is an area I used to miss sometimes.
This area is dictated by the style:
TD.ms-rightareacell div.ms-pagemargin
If you don’t make amends for this, you’ll have the lovely default blue sticking out from your design. There are many others which I’m not going to name here but here are a few tricks I’ve learned about applying custom CSS to the application.master.
- Once you nail one down, copy it and SAVE it in a safe place. I have a “neutral” colored one that I like to use now which generally applies to most client’s needs. Although on the heavily branded ones, I still miss the above mentioned one until I do my style check.
- Always check the three pages listed below to make sure you’ve covered your bases regarding styling the “admin” pages. They each have some slightly different classes you might not have covered in your CSS for your own master.
- Site Settings (be sure to style the .ms-linksectionheader — it’s just a nice touch for your clients)
- All Site Content
- Site Navigation Settings (i.e. the Navigation link off of the Site Settings page)
I realize none of this is groundbreaking by any means but it is something that I found frustrating at first until I nailed down the basics and most importantly, kept a copy!
