Question

This is the fiddle I’m messing around with

Is there a way to increase the space between what I have floating right and what’s floating left? I just want to increase it 10px or something arbitrary like that, so I don’t want to use width:20% Here’s a pic for reference:

Yes, all you have to do is specify a margin for the elements:

fieldset {
    float: left;
}
select {
    float: right;
    margin: 0 0 0 2em;
}

Or:

fieldset {
    float: left;
}
fieldset label {
    margin: 0 1em 0 0;
}
select {
    float: right;
}

JS Fiddle demo.

Or, simply assign a width to the fieldset elements:

fieldset {
    float: left;
    width: 15em;
}
select {
    float: right;
}
