How to add color stops in gradients for rows?

Hi,

I’m currently working on a layout using tagDiv Composer and I’m running into a limitation with the background gradient options for rows.

Here’s what I’m trying to achieve:
I want to create a vertical gradient that starts with black, and stays solid black up to 70% of the row height. Then, from there, it should fade smoothly into white towards the bottom (100%).

In CSS terms, I’d normally do something like this:
background: linear-gradient(to bottom, black 0%, black 70%, white 100%);

But in tagDiv Composer, when I add a background gradient to a row, I can only:

– Select two colors
– Define the gradient direction/angle

There seems to be no option to control color stops or percentages of where the transition happens.
At the moment, it just fades evenly from one color to the other across the entire row.
