Is it possible to place a unique id in custom css?

My unique id is generating a value and I need the CSS width to use that value and apply it.

Ex.

.Css-class {

width: {uniqueId}%;

}

I've tried to apply it as a inline style as well but that doesn't work either.

<div style="width: {uniqueID}%;></div> 

The inline style only seems to work on the thank you page but that is not what I'm trying to achieve here.

Unfortunately, it is not possible to pass the value of the unique Id field to the CSS. To do this you can download the source code of the Form.

Let us know if you have further questions.

Thanks.
