Using Phoenix.VerifiedRoutes within TailwindCSS arbitrary rules
Hi,
In the past when I needed to set the background image on an element I gave up Verified Routes and wrote something like bg-[url(/images/background.svg)] in my template. The Tailwind compiler then generates a CSS class that sets the background to the image.
I found myself in need of doing it again, and since I couldn’t find an existing thread on using TailwindCSS + VerifiedRoutes I decided to ask – is there a way to use both together?
I tried this but it doesn’t work, because I understand the Tailwind compiler sees Elixir code as is and not the compiled string after the ~p sigil is processed:
<div class={"bg-[url(#{~p"/images/background.svg"})]"}>...</div>
Another idea, which I did not try, would be to add some kind of plugin in tailwind.config.js similar to how Heroicons are made available. I thought perhaps someone in the community has an easier way to offer?

<div class="bg-[url:var(--bg-image)]" style="--bg-image: url(…)">
That one works. The style can be dynamically set in that case.

My solution to a similar problem was to use css variables and to extend tailwind background image:
{
extend: {
backgroundImage: (theme) => ({
custom: "var(--bg-image)"
})
}
}
this requires setting the --bg-image css variable to url(/some/image.png) which can be done with an inline style, kinda like this:
<div style={"--bg-image: #{url}"} class="bg-custom">
something here
</div>

Hmm, wonder if the nested double quotes are the problem…
class={"bg-[url(" + ~p"/images/background.svg" + ")]"}
class={"bg-[url(#{~p'/images/background.svg'})]"}
Just to rule that out, I’d give those a shot ¯\_(ツ)_/¯
