How do I get my product listings wider?

Here is a picture of my product listings on my form. How do I get them to appear wider and not so crunched and squished on one side?

My videos also extend beyond the green. Is there a setting that I can check so people will be able to preview the entire form before filling it out?

Hello,

Please inject the following css code to your form to fix the layout for the form width you've selected: 

#id_10 {

  width: 100%;

}

#customFieldFrame_8, #customFieldFrame_5 {

  max-width: 450px !important;

}

Thank you.

Thank you! Can I use this same code to widen any other form or just this one? I don't know how to do coding and chose jotform because it says it is the easiest! 

Hello again, 

The code was developed for this particular form. Sometimes css codes are re-usable, but I can't be sure as I haven't seen your other forms. 

If you need assistance with any other of your JotForm, just drop us a line here. 

Thank you.
