Force question label text to be full width of form

Hi

I dont know how to describe this but the question text over the radio buttion i want it spread over 790px. I done in designer mode with css, but in preview and live its till line in the left. 

I tried with agaile to left, right and auto. IF i out on agaile top, the qeustion label/text are disappearing 

Change your code to:

.form-label.form-label-left {
    width : 790px !important;
}

It looks like something in the theme applied to your form the overwriting your CSS.  Adding the !important tag will ensure that your code is what is shown rather than the theme.
