[Plugin: Participants Database] Displaying Images

I tried to change the colour of the Sign Up error message box in the CSS stylesheet of the theme I’m using at present, but I was unsuccessful. I tested the Sign Up page using a few different themes and the error box background appears to be a light pink colour in all the themes I tested. Is it possible to change the pink border, and the light pink background colour in the error message box to darker shades of pink in Participants Database Plugin?

You’ll need to put something like this in your theme stylesheet:

#content .pdb-error {
background-color: (your background color);
box-shadow: 0 0 6px (your border color) inset;
}

Just replace the parentheses with the color values you want.

Just to let you know my problem is resolved. I tried the fix you gave me, but I wasn’t successful. In the meantime I also contacted the theme developers and they sent me a fix. As advised by them, I uploaded the Plugin Jetpack, using the CSS edit feature I entered the code they gave me into the theme stylesheet, and it worked. Now I can use this theme successfully as well as your Participants Database Plugin on my website. This is a win, win outcome – happy days.
