styling forms with current style already on my other forms

This is a fairly customized form styling and it looks like he targeted items via form ID, for example, see this Screenshot

How versed are you in CSS? Do you no longer have a relationship with your developer?

Well, you could try simply daisy chaining the styles they have written. For example, one snippet in your stylesheet is:

[css]
#gform_wrapper_1 h3.gform_title {
color: #F1B811;
text-transform: uppercase;
width: 100%!important;
clear: both!important;
display: block;
float: left;
font-weight: normal;
font-family: 'IMPRISHANEWRegular';
}

So you could try replacing that with:

[css]
#gform_wrapper_1 h3.gform_title, #gform_wrapper_7 h3.gform_title {
color: #F1B811;
text-transform: uppercase;
width: 100%!important;
clear: both!important;
display: block;
float: left;
font-weight: normal;
font-family: 'IMPRISHANEWRegular';
}

So anywhere you see a style declaration that contains #gform_wrapper_1 you can comma separate it by copying and pasting the line and then using #gform_wrapper_7.

If this makes you uncomfortable, I'd recommend against it.

where do i find these? in the CSS file for forms in the GF folder?

for the most part i got it! a few style things are beyond me.

1. in IE 8and 9 and chrome the final page of the form "previous and submit" - the submit is sticking out to far to the right and this does not happen at the end of the other "diamond buyers" form?
2. in ie 8, text entered into the input fields is not centered vertically
3. the multiselect field in the second page of the form is white with a white backgound, how do i fix this.

finally, what is the easiest way for me to increase the font size in all forms?

thank you sooo much

i tried for 2 hours and cant figure out why, since i basically duplicated the style

I get a 404 on that page link:
