Recently we talked about that in Google Chrome Canary to test the new browser interface with Material Design. Now this can be done in stable version of Chrome.
So first of all you need to update Chrome to version 68. You can then enter in the address bar, the command chrome://flags/#top-chrome-md and then press Enter.
Page opens with the experimental settings where the opposite is highlighted in yellow option, it is necessary to choose Refresh (if you have a computer with a touch screen, then Refresh Touchable). Then restart Chrome using the blue button in the lower right corner.
After restarting, you will get Chrome with an updated design.
