Creater view color and layout

Creater view color and layout

Good evening,

I have two questions that I have failed to find the answers to in the documentation. Any help would be greatly appreciated.

1. I have a view that I have embedded in another website. I would like to modify the colors to fit the colors of that site.
 I have tried the commands at https://help.creator.zoho.com/Style-based-URLs-for-Embedded-Forms.html#6._View_Customization . Some of the commands work, but those that are intended to change the color have no effect. Anyone knows what I am doing wrong?

2.I am wondering if a layout like the following would be possible?:

Column1 Column2 Column3
C   -o   -l   -u   -m   -n    -4
Column1 Column2 Column3
C   -o   -l   -u   -m   -n    -4
etc.
As a way of avoiding having to squash too much data together on one single row.

Again, any help would be appreciated.
Thanks
