Hi Azin,

thank you for reaching out to us

Customize General Color setting will influence the panel:

Are you trying to change the background behind the listed appointments as well?

Hi Azin

If you would like to modify the look of Amelia forms beyond what can be achieved through the general customization I can explain how to find and copy the selectors you need to use to style something.

Right-click on the part you wish to hide and inspect the element:

Then, when you hover over the code, that section will be highlighted in the modal. Right-click on the code that highlights the entire div, and go to copy/copy selector:

Paste that selector, and add "display: none !important;", like this for example if you want to hide something, different code would be applied if you want to change the color of course

#tab-extras {
display: none !important;
}

Certain selectors can't be combined, so if it doesn't work when you separate them with a coma, simply add another selector below }

If this doesn't help either, we can recommend these services for customization
