just in case anyone comes across this fix in the future, there are a few missing elements that confused me for a while. Here's the full line of code -- thanks Dory, very helpful!
.mktoForm label[for="YOUR FIELD NAME"] {
float:right!important;
margin-left: 10px!important;
width:316px!important;
}
I also ran into some issues with the field name because it was a field from Salesforce, synced to Marketo, so I had to use the API name, not the field name listed in the form. I also added a margin-right field to fine-tune to my specific form, so there may be a bit of tweaking still to do for you.
Great solutions!
Though in cases where you have links in the label name - ie I agree to the T&C(url), the rich text or setting values for checkboxes doesn't seem to work.
