 <p>Change the module script to remove the reference to material.svgAssetsCache and the demo will run but without the final row of buttons - which reference "local" image resources.</p> <p>If you grab a copy of the icons(<strong>bower install material-design-icons</strong>) and locate the relevant 24px .svg files and pop them in (say) /img/icons/ from the root of your web site (adjusting file names and path as required) then even this section will work just fine. </p> <p>The demo is rather off-putting when you think about it as it is likely to be chosen as a first stab at trying things out yet it only works within the CodePen sand-tray.</p>
