dhtmlxToolbar uses the Material Design-based icons by default. However, you can use any other icon font pack, if necessary. For this, you need to include the desired icon font on a page and apply icons for Toolbar controls.

For example, you can use the Font Awesome icon pack by including link to its CDN after the source files of dhtmlxToolbar as follows:

<script type="text/javascript" src="../../codebase/toolbar.js"></script>
<link rel="stylesheet" href="../../codebase/toolbar.css">
<link rel="stylesheet" href="" 

Then you can use the name of the icon as the value of the icon property in the object with the control parameters for toolbar:

var toolbarData = [
    { type: "button", icon: "fas fa-bold", twoState: true },
    { type: "button", icon: "fas fa-underline", twoState: true },
    { type: "button", icon: "fas fa-italic", twoState: true },
    { type: "button", icon: "fas fa-strikethrough", twoState: true }


There is a possibility to make changes in the look and feel of a toolbar. For this you need to take the following steps:

  • add a new CSS class(es) with desired settings in the < style > section of your HTML page or in your file with styles (don't forget to include your file on the page in this case)
    .my-first-class {
        /*some styles*/
    .my-second-class {
        /*some styles*/
  • specify the name of the created CSS class (or names of classes separated by spaces) as the value of the css property in the Toolbar configuration:
    .my_first_class {
        /*some styles*/
    .my_second_class {
        /*some styles*/
var toolbar = new dhx.Toolbar({
    css:"my_first_class my_second_class"
