I need to change the color of the background, the font size and the font weight from the warning message
I tried achieve this via javascript, to get the warning html id and set the color. Via console I can do it because the whole page has already loaded and rendered.
However, if I create a webresource and ask it to load with the onload function in the form. It won't change because the whole page was not fully loaded yet.
It would be good if there is a way of achieving it with a css web resource as well.
Is there anyway we can change it?
