changing the file shortcodes.css

[lysaha]

Good afternoon. There is a problem, can’t change the font size, as prescribed !important to change the file shortcodes.css downloaded via ftp the file you changed I need a line of code threw back, but no change occurred, that is, using the view source in the browser displays the old code. If you go through the settings of wordpress appearance editor to open shortcodes.css changes appear. How can I solve this problem? The code will be applied.
.minti_zooming_slider .flex-control-nav li .nav_title h6 {
width: auto;
margin: 0 5px;
padding-top: 15px;
font-size: 11px !important;
color: #666666;
text-align: center;
cursor: pointer;
