Good evening Bfarber,
I may have a solution to replace the FA icons with images!
Usually to add an image, we use the tag
<img src = "mon_image.jpg" alt = "mon_image" title = "mon_image" />
Since we are using the <i> tags for Font Awesome, displaying an image will not use the <img> tag, but we will use the FontAwesome code with the image in the background.
Replace some FA icons with a classic image.
For modification, only CSS modifications are required. We will take the case of the .fa-remove icon which displays the following cross x.
The .fa class declares the font, since we will use a background, there is no need to modify it.
The .fa-remove: before class declares the character you want to use .fa-remove: before {content: "/ f00d"; }, it is necessary to cancel it so as not to display the FA icon.
Since we do not want to replace all the icons, it is important to target the modification.
... To be continued,
Regards,
Claude
