PHP:

 

would you like all the borders to have a bolder border around them or just some of them?

If you want all the border colors changed then find:

input {
    padding: 2px;
    border:1px solid #eee;
    font: normal 1em Verdana, sans-serif;
    color:#777;
}

Code (markup):

and change to:

input {
    padding: 2px;
    border:1px solid #000;
    font: normal 1em Verdana, sans-serif;
    color:#777;
}

Code (markup):

Or whatever color that you would like... you can also change other things of the input like the size of the border (1px is the default with your css)
