Are there any Elixir or Phoenix functions that escape CSS like CSS.escape?

I want to securely escape values for attribute selectors.

```elixir
<style>
div[value="<%= "[value with double quote]" %>"] {
  background-color: blue;
}
</style>

<div value="1">One</div>
<div value="2">Two</div>
<div value="3">Three</div>

```

I would expect something like that to be in `phoenix_html` if it existed: [Phoenix.HTML — Phoenix.HTML v4.3.0](https://hexdocs.pm/phoenix_html/Phoenix.HTML.html).
