How can I add border to JqTree?

Question

I tried this

.jqtree-tree .jqtree-element {
    border-color: black;
    border-width: 10px;

}

Probably I am missing some elements to whom this CSS should apply

Answer 1

You can try like,

.jqtree-tree {
    border-color: black;
    border-width: 10px;
    border-style: solid;
}
