Pls see the first picture below where i named one of my section as “picleftsidebackground”, The reason to name class is to use the same settings for some more sections later in the page.

Then i wrote content css for the class above

After inspecting in browser i can see some settings appeared but not giving desired result.

Instead of CLASS if I define this in ID tab, and writing as #picleftside… it works. But because I want to define as class what is the solution. Please can you help me to use the class extensively so that I hv not to repeat those settings. I know i can copy template or duplicate but that not helps my purpose as when i want to change the background later, for all the sections where I used this CLASS, i will simply change in css window.
I tried to search in current forum but somewhere it said you need to name it differently, Why i need different name as I do not want for the particular element, i want a general CLASS.
