I would like to change the default bootstrap icon for accordions
Instead of the default arrow icon, I would like to use the <i ></i>
and the <i ></i>
Current result:
As far as I know the default arrow icon comes from here (truncated):
.accordion-button::after {
background-image: url(data:image/svg xml,);
}
And it's basically set as a background-image.
When the user toggles, the background image is rotated 180 degrees:
.accordion-button:not(.collapsed)::after {
background-image: url(data:image/svg xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='#0c63e4'%3e%3cpath fill-rule='evenodd' d='M1.646 4.646a.5.5 0 0 1 .708 0L8 10.293l5.646-5.647a.5.5 0 0 1 .708.708l-6 6a.5.5 0 0 1-.708 0l-6-6a.5.5 0 0 1 0-.708z'/%3e%3c/svg%3e);
transform: rotate(
-180deg);
}
The first thing that comes to my mind is to replace both svg's for the desired bootstrap icons svg's and remove the rotation.
So I tried to replace the current SVG with the bootstrap icon svg:
.accordion-button::after {
order: -1;
margin-left: 0;
margin-right:0.5em;
background-image: url(data:image/svg xml,%3csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='#212529' fill-rule='evenodd' d='M8 15A7 7 0 1 1 8 1a7 7 0 0 1 0 14zm0 1A8 8 0 1 0 8 0a8 8 0 0 0 0 16z' d='M8 4a.5.5 0 0 1 .5.5v3h3a.5.5 0 0 1 0 1h-3v3a.5.5 0 0 1-1 0v-3h-3a.5.5 0 0 1 0-1h3v-3A.5.5 0 0 1 8 4z'/%3e%3c/svg%3e);
background-color: white;
}
Unfortunately it did not work. Did I put the svg code wrong? is there a better way to achieve this?
(feel free to edit the code and try the svg code of any bootstrap icons)

I found a solution, basically we need to encode those bootstrap icons svg's in order to use it as css background-image.
Here is an online solution that I found.
So now, with this code:
.accordion-button::after {
order: -1;
margin-left: 0;
margin-right:0.5em;
background-image: url("data:image/svg xml,");
background-color: white;
}
It works!

Sass option:
You didn't mention if you're using sass (that I could see) but if you are, Bootstrap 5 provides the 2 sass variable for accordion icon states which you can override:
$accordion-button-icon: url("data:image/svg xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='#{$accordion-icon-color}'><path fill-rule='evenodd' d='M1.646 4.646a.5.5 0 0 1 .708 0L8 10.293l5.646-5.647a.5.5 0 0 1 .708.708l-6 6a.5.5 0 0 1-.708 0l-6-6a.5.5 0 0 1 0-.708z'/></svg>");
$accordion-button-active-icon: url("data:image/svg xml,<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 16' fill='#{$accordion-icon-active-color}'><path fill-rule='evenodd' d='M1.646 4.646a.5.5 0 0 1 .708 0L8 10.293l5.646-5.647a.5.5 0 0 1 .708.708l-6 6a.5.5 0 0 1-.708 0l-6-6a.5.5 0 0 1 0-.708z'/></svg>");
https://getbootstrap.com/docs/5.1/components/accordion/#variables
Bootstrap 5 has an escape_svg
function too (i think that's what it's called) to escape the characters in the SVG too.
You'd need to include your variable overrides as outlined here: https://getbootstrap.com/docs/5.1/customize/sass/#variable-defaults
Might seem a lot of work but once it's setup with sass it becomes easier to override & extend things in Bootstrap this way.
