Change the colors, font and floating button so the widget matches your website.
You can match the widget's colors and font to your brand. Changes apply right away on your site: you don't need to copy the code again.

Check the Preview as you change the colors.
Make sure the text is easy to read on the background. If you don't like a color, Reset to default values brings everything back to the original design.
Under Font you can keep the system font or choose one from the list. If your site uses a similar font, the widget will blend in better.
Under Floating button choose one of the predesigned styles and its Button position (left or right). It's only used if you pasted the floating button code on your site. The button text follows the language of the code you copied.

Click Save design (in Transportation, Save appearance). Reload your site to see the change.
