WordPress CSS problems with controls

Yes, this can easily be cleaned up with a little CSS. You can start by using the browser’s inspector, hit F12 to open it, and select the element you want to style.

See if that form or something around has an ID, use that to target each element so you don’t effect other pages or unwanted elements.

Here are couple example that might help.

#myFormID label,
#myFormID input[type="text"],
#myFormID select {
    display: block;
}

That will put your labels and form elements on different lines.

The best thing to do is just inspect the page and start playing around with the CSS.
