Step 3

Select the "theme.liquid" template from the layout folder and go to the bottom of the editor and paste your Userlike Widget code before the "</body>" tag. I Hit "Save" and your Shopify shop will be equipped with Userlike.
To avoid CSS conflicts with the chat client, we advise you not to use iframe { !important } in your CSS. Better be more specific and exclude the Userlike chat client by using iframe:not(.userlike) { !important }.
