Custom CSS

[Ubafeesh]

When attempting to create custom CSS, how do I target the correct div I'm trying to affect?

For instance, the top bar widget of my master file is Header, but this is not the div name nor is the ID container-2. 

I'm trying to do something as simple as changing root mashup (body) background.

I'm a web developer so perhaps my understanding of how this works within thingworx is a little skewed.

Thanks!

Ok I think I see that you have to use CustomClass to name the DIV. 

The tutorial says "click the CUSTOM tab" to add a CSS block but I don't see that anywhere.

Is the NEW COMPOSER different than the 8.2 trial? I'm not seeing any CUSTOM CSS tab anywhere.

New Composer is available with the 8.2. You need to turn on new Composer features under Administrator > Preferences > Turn on New Composer Features

Here is a Guide to getting started:

Often the div ID has root_ pre-pended to the ID you see in Mashup Builder. For example, if the ID in Mashup Builder is container-2, the div id is root_container-2

Thanks for your response!

There has to be a way for me to SEE the div name tags somewhere?
