a <div>
can be focused if it has a tabindex
attribute. (the value can be set to -1)
For example:
$("#focus_point").attr("tabindex",-1).focus();
In addition, consider setting outline: none !important;
so it displayed without a focus rectangle.
var element = $("#focus_point");
element.css('outline', 'none !important')
.attr("tabindex", -1)
.focus();
