Sounds like your experience with CSS is limited. In the folder you will have a file with any name, "Mine is called "mycss.css". In this file you will have a bunch of CSS code. a snippet of mine looks like:
.k-context-menu.k-menu-vertical>.k-item>.k-link {
background-color: #FED7AA;
font-size: 14px;
border-radius:6px;
box-shadow: 5px 2px 5px 0px rgba(50, 50, 50, 0.75);
}
.header {
background-color: #ffffd0;
background-image: url('../CSS/ALC/americanLumber.gif');
background-repeat: no-repeat;
vertical-align: top !important;
background-size: 250px 30px;
}
.customerGraph .k-window-actions {
display: none;
}
.textForHeader {
margin-top: 5px !important;
padding-left: 300px;
padding-top: 10px;
font-size: 10px;
}
.bigTextForHeader {
padding-left: 50px;
font-size: 14px;
}
Then, in the CSS class property of your content panel you have the name of the class (no .css, just the name of the class) . Look at the file attached.
