I want to add the class ms-hideto the body of my master page depending on certain conditions.

I'm trying to do something like delegate controls where, based on a feature I add or remove this class from my body.

I'm doing a lot of DOM manipulation on my project sites and I want to hide the body until it's ready then fade it in.

One option, showing the power of CSS

add a STYLE tag to your document, preferably in the HEAD, but can be placed anywhere

<style id="hiddenHTML">
  :root body{

This hides the body tag, but you can still do DOM manipulations

Once you are ready you disable the whole STYLE definition

  • Well I can already use ms-hide for styling so that's fine. My issue is that I need the styling to be determined based on some variable server site or on render. Essentially, I have /projects/home (I don't need to hide things there) but then I have /projects/proj-2016/1( to n) So I'm trying to find a way to have this class applied to the body depending on what collection I'm in or if a feature has been enabled (like delegate controls) etc.

  • Apply a UserCustomAction ScriptLink so it executes on every page and whack that class in with JS Apr 7, 2017 at 18:44
  • I'll try that. Hopefully it's fast enough to apply the styling right away. I was assigning styling on $.ready but then it would stutter between displayed and hidden, then displayed again when my DOM manipulations where done.

  • That's why you do the reverse with the STYLE, hide always and show on /projects/home Apr 7, 2017 at 20:13
