I have a modal that pops up when the site detects it's on IE11. The modal is in a cms block so that the client can edit it. I have created a reference container with a custom phtml and put the script in there. But it's not working! Is this because the script is in a phtml file? and if so can I call a block using php in a js file? Please note that I'm trying to detect chrome in this example as I'm on a mac.
