Toolbar height in layout

I made a small change the height of the toolbar. When I layout.attachToolbar(), the new height is not used, the standard toolbar height is used. How/where do I change it to accommodate my new toolbar height?

Except changes in css you need to modify dhtmlxcontainer.js, line 901:

document.getElementById(this.vs[this.av].toolbarId).style.height = “29px”;
