Ok, I had this same problem and became very frustrated, because I don’t know any coding (didn’t even know where to find the design sheets). After hours of reading tutorials on the web, here is my step-by-step explanation of the solution I found:
If you mouse over the “Plugins” tab on your dashboard, you’ll see something called “Editor”. Select it.
When you get there on the top right you’ll see a place where you can pick the name of the plugin you want to edit. Select “GT Tabs”.
Under the “Plugin Files” menu on the right side, pick gt-tabs/style.php.
Scroll down until you see this block of code:
ul.GTTabs li
{
<?php if ($GTTabs_options["layout"]=="horizontal") echo "display: inline !important;"; ?>
font-size: <?php echo $GTTabs_options["font-size"]; ?>;
line-height: normal;
background: none;
padding: 0px;
margin:1em 0px 0px 0px;
}
After line-height:, where it says normal, replace this with a number. For me the right value was 1.5. The way to think about it is the same way you think about the spacing between lines in a text document. Each row of tabs is a separate line of text and 2 would mean double spacing. That line for GT Tabs for me now looks like:
line-height:1.5;
Hope this helps someone!
