Child theme styles.css not over-riding Parent themes' CSS

Hi All,

I’ve done a search (both here, and across the web) to find a solution to my problem but was unsuccessful.

Was hoping someone could/would help me with this.

Here’s the URL for my website (if that helps):
http://www.synergyintegration.com/siwebsite

So, the thing is…(for now) I’ve changed only the background color of my website (in my child-theme’s style.css file) i.e. that’s the only over-riding element that I’ve styled…and it seems like that that is indeed getting loaded – and the required color is being displayed (albeit for just a brief second)….and then that is replaced with the background color of my parent-themes’ style.css file.

I have no idea why/how this is happening…since even the “view source” seems to say that the main stylesheet is being loaded from the child-theme folder.

Would anyone anyone be able to throw some light on this and/or help provide me pointers as to where/what I should be looking for?

Appreciate the help.

Much thanks,

WPB
