Using a custom TinyMCE config is fantastic. You can use it to edit an entire block of content, even adding images and providing a select drop-down of classes to add to the image. This lets you take advantage of Bootstrap’s extensive stylesheet.
"image_class_list": [
{
"title": "None",
"value": ""
},
{
"title": "Left",
"value": "rounded float-left mr-5 p-1 border border-secondary"
}
],
