Steps to reproduce the issue

safari on Mac

Edit atum template style in Joomla admin
Colour Settings tab

Expected result

I think the color selector boxes should be full height of the input area - or maybe a bootstrap prepend area?

"Choose your hue value for the dark template colour" on one line

Actual result

Choose your hue value for the 
dark template colour
