Align and Adjust Fields Using CSS Codes

I tried the Advanced Form Editor and it made all my text boxes the same width. That was okay but it screwed up the Name Widget. I fooled around with the CSS but it pretty much sucks. I couldn't get the Last Name sub text under the Last field. 

Is there a way to undo all the stuff the advanced editor did?

Hello,

I've inspected your form and checked the codes applied. It seems fine right now, have you figured out what went wrong? Upon checking in the screenshot you've provided it seem right, maybe you've just forgot to save your changes in the CSS area.

If you wish to undo all the changes you've made in your form especially in the CSS area, you can just delete all the codes you've injected and it will revert your form to the point wherein no styling codes were applied.

Please let us know if you need further assistance, we'll be glad to help. Thank you!

Look at the subtitle for Last Name.

Thank you.
The Last Name subtitle is aligned okay in the Preview but is wrong in
Builder mode.
How do I undo the Advanced Editor changes (not just the CSS) and get it
back to the layout settings I made using the Builder widget options?

Please remove the custom CSS code to your form and replace it with this:

#first_3 {

    width : 100% !important;

}

#last_3 {

    width : 100% !important;

}

Thanks, and how do I undo the changes made in the advanced form editor?

Hello,

If you wish to revert back your form to a certain saved point, I would suggest you to look after your Form Revision History. From here you can find all the time to time changes you have made to your form.

If you need further assistance, please let us know, we'll be glad to help. Thank you!

I tried that (width 100% !important;} but it didn't help. The Advanced
Editor screwed up all the text box widths and I can't adjust any of them
now.

I think that I've found a solution that meets the requirements, please remove all the existing CSS code and add this one:

#first_3 {

    width : 200% !important;

}

#last_3 {

    width : 200% !important;

    margin-left : 100%;

}

#sublabel_last {

    width : 200%;

    margin-left : 100%;

}

Don't hesitate to ask for help if you need further assistance.
