[CLOSED] how to change grid font size

[sharif]

hi guys,

can you show me an example how can I change the grid font size. I tried to add it to StyleSpecs. I changed the color but not the size then I created a class and added to to CtCls and changed the color but not the size too

thanks

.x-grid-cell-text {
    color:Red;
    font-size: 5px;
}
