Different Appearence in IE / Chrome / Firefox

ok, im here "Editing file "/elements/designlayout.php" in template "hot_clinic"".
it shows me a text editor, whats the code i have to add and where?
thanks a lot!

ok i did it.
in sparky i add the row as you explain, then in themplate_css.css (in hot_clinic template) i add the code under "/******* CUSTOM ROWS AND CELLS STYLING *******/"
but it didnt fix it

solution:

in template_css.css add add "margin-top:30px" in this line:

.sparky_home .content_sparky .cell_pad {
margin: 0;
margin-top:30px;
}

thank you very much for your time, post solved.
