Hello,

I have used this in my custom.css:

.sub-header-row th { background-color: #547599; color: #FFFFFF !important; text-align: center; } 

and I also tried this: <style type="text/css">.sub-header-row th { background-color: #547599; color: #FFFFFF !important; text-align: center; }
</style>

As I am trying to have the headers and subheaders of my array questions have a grey coloured background. I had used "grey" to replace 547599 also, and this did not work. I am wondering, what am I missing?

Thank you!

Maybe because this color is named "gray"?

Hello,

But even if I use "gray" or any other html colour name (or #), the header background does not change colour at all.

As always recommended, use a webdevelopment tool to investigate the classes involved.

So the class is ".ls-heading"
Either you may color everything in the same color with  

Or you distinguish between the parts like

Hm, the editor has its own will, as often.

Either
Or

/* the left empty square */
  .ls-heading td {
  background-color:green;
  }
/* the default header */
  .ls-heading th {
  background-color:blue;
  }
/* the inserted header */
  .ls-heading th.inserted-header {
  background-color:yellow;
  }

Hi Joffm,

Ah okay, I see - this works great. Thank you very much. I have another subquestion: 

With the image I attached, the lines (or borders) that separate the columns and rows get hidden by the background colour. Would the only solution be to lighten the shade of the background colour of my choice or is there an alternative way to ensure that there is no "blend"?

I hope I am making sense.

Thank you again.

   

Hm,
if you set the color of the background to the same or nearly the same as the borders, you won't see them.
Obviously you have to change one of the colors, either the  background or the borders

Makes sense. And how would I go about thickening and/or changing the colours of the borders?

Set the background for all parts separately
And to address the left upper border, add
xxx and yyy: your desired values.
