How do I add a color background to a specific text box

[SandyS09]

I have created Heading Text Boxes for my newsletter with a black background and gold text. Up until now I have been able to copy and paste the box where I needed it I can't seem to do this and I can not seem to find a way to accomplish this task now. I want to add a color background to specific text boxes. Thank you @sshargel

Hello @SandyS09 ,

Even if you copy a block, you can still overwrite the background coloring for a row or block using the fill option for the side menu: 

Using pre-built layout blocks, such as those generated from a PDF -> email conversion or from the layout blocks on the lower lefthand menu, may contain several block types together. The pre-built layouts would all be tied to the same floating side-menu buttons.

I'm having the same issue with my headings. The side menu only appears for some of them.
