Finding these CSS odditiies

Its like finding Waldo. Google shows it clearly but I can not locate it in any of the Weebly CSS files

First is just need to left justify a title:

<H2> .wsite-content-title

Also have some mystery cells/columns/divs preventing me from centering a login. In Weebly these columns do not exists. There is a script to HIDE extra logins which may be contributing.

Ive copied the CSS from Knack into Dreamweaver and used SEARCH to find wsite-conent-title but can not. Thanks!

Sorry for not being clear. Yes, inserting the Knack embed into Weebly. Cant locate that CSS class in any code.

I don't quite understand. Are you embedding your Knack app into a Weebly site?
