CSS:
#textField_ccdbc05b div div {
width: 250%;
background-color: aqua;
border: 1px solid black;
}
Show the field in your custom form that corresponds to this CSS, please.
Change the width statement to be 700px instead of 250% and test.
Also not working as desired in 7.5. May be a bug with this type of field, not sure. Feel free to open an SR and inquire officially.
Thanks for your help and for checking under vRA 7.5
How do I open an SR?
