I'm glad I stumbled on this PHP 8 info. I have been working with Coffee Cup support for a long time trying to get my web form builder script linked to Site Designer as per their enterprise example. Support has been quiet for a few months now. My hosting service is using PHP 8. Web form builder works great when it is added as an html element, however google gives warnings since the height of the fields are too small. The pixels height needs to be increased, but support has said that wfb can't be modified to increase the height of the fields. Can anyone help with this problem?

You can set styles with straight js or jquery. You can also override the css.
These are targeting by input name. Adjust the text1 to your input name.
JS added to a html element.

Where does this script go? I have the script from wfb imbedded as an html element on my contact page. Does this script get added to the wfb script in site designer? Can you have multiple scripts added to the html element?

Use an html element within the Form Builder application and add it there. It's probably best to place the html element below the inputs that you want alter.

I have tried adding the script you listed with my inputs into SD and also WFB, but can't get the height of the input field to change. I'm not sure what you mean by using an html element within the form Builder application. Any additional help would be appreciated.

Fantastic! Thank you so much. The input boxes are now at 48px and meets google requirement. The input characters still show on the smaller side. Can they be enlarged? Is it possible to make the checkbox larger in WFB? Just in case google wants it larger also.

The second line should've increased your font size. Make it more.

You can also apply regular css on elements.

The 18pt shows up on my Stoverimaging.com contact page which is hosted on dreamhost with php 7.4. The text area field still has small letters. My LLPyroArt.com site still has all small letters and it is hosted on dreamhost with php 8.
I will try the css. Thank you.
