Why are my labels wrapping rather than extending across the page?

In the builder, the labels show as extending across the form, but in the preview, they are wrapped in a space about 1/8 the size of the form. I've checked all the settings and can't figure out what to do. 

This is happening because the width of the label is set to 150px. Please inject this custom CSS to fix the issue:

.form-label.form-label-auto {
   width: 100% !important;
}

Thank you. What would be the CSS code to do that for the options in a single choice or multiple choice question?

Here's the CSS code to increase the width of the options in single choice and multiple choice fields:

.form-radio-item, .form-checkbox-item {
max-width: none !important;
}

[data-type="control_radio"] .form-input, [data-type="control_checkbox"] .form-input, [data-type="control_radio"] .form-input-wide, [data-type="control_checkbox"] .form-input-wide {
max-width: none !important;
}
