Hello again..
maybe you are annoyed with me... but i swear that is this the last question I have to make.
I have placed an ARI DataTable module at:
nazo.housos.gr/index.php?option=com_content&view=article&id=140:etairiesenapgr&catid=59&Itemid=58
How can I make the first column fonts to be 1-2 size bigger than the other column fonts?
In my last question you gave me the following CSS code, which I have entered to the CSS styles area box.
---------------------------------------
.dataTables_wrapper
{
font-size: 10px;
}
body .floatbox
{
overflow-x: auto;
}
body .floatbox,
body div#wrapper div.wrapper-br
{
overflow: visible;
}
-----------------------------------------------
Now I want only the first column font, to be 11px and bold, and the other remain at 10px
Thanks in advanced,
Yours sincerely
