Appearance (margins and style)

Hello, please let me now that your widget is cool!!!!

I want to include some user fields but I’m not able to use the css propertly. For my what is important is to create an space (margin) between the different rows envolved (input field, user field1, user field2,…). Also it would be cool if I could use my current theme CSS for buttons:

I selected the Relax CSS style but it is not working.

I have try the solution you gave in the Apparence form post but still not working even including the css you suggested:

#wordpress_file_upload_block_1 td.file_td_clean {
max-width: none;
}
input#fileName_1 {
width: 200px;
padding: 10px;
background: #f8f8f8;
}
form#uploadform_1 {
width: 100px;
height: 40px;
}
input#input_1 {
width: 100px;
height: 37px;
background: black;
border: none;
color: white;
margin-top: 1px;
margin-left: 4px;
}
input#input_1.file_input_button_hover {
box-shadow: inset 0px 0px 4px #fff;
}
input#upload_1 {
width: 100px;
height: 37px;
background: black;
border: none;
color: white;
margin-left: 4px;
}
input#upload_1:hover {
box-shadow: inset 0px 0px 4px #fff;
}
input#upload_1:disabled {
color: silver;
}
div#wordpress_file_upload_subfolders_1 {
width: 404px;
}
span.subfolder_dir {
height: 25px;
display: inline-block;
margin-top: 10px;
}
span.file_item_clean.subfolder_label {
width: 140px;
display: inline-block;
}
select#selectsubdir_1 {
width: 264px;
height: 40px;
background: #f8f8f8;
}

Thank you!!!
