I've set up a text format called contributor and have allowed tags in the allowed tags html filtering.
I've configured CK by disabling ACF. I've also put in "config.allowedContent = true;" into the Custom JavaScript Configuration textarea, in the Adavanced Options section. All CK profiles I've done this for. This usually works for me, btw.
I have the styles dropdown in my toolbar for the CK profile that uses the contributor text format. I've copied the configuration.styles.js file into my theme and have created a style to float my images to either side- left or right. Coding is like this:
...
{
name: 'Image on Left',
element: 'span',
attributes: {
'style': 'float:left;margin-right:1em;'
}
},
{
name: 'Image on Right',
element: 'span',
attributes: {
'style': 'float:right;margin-left:1em;'
}
},
...
I see the styles for floating in my dropdown and when I apply them they seem to work (in the CKEditor); I can view source while still using the editor and see my image I had selected is wrapped in a span with a style attribute. But when I save my node, the span tag is there but the style attribute is stripped out. I've tried altering my JS to apply the float style to the image tag, and I get the same thing. I can see the style="float:left;margin-right:1em" in the img tag in the html source. Seems attributes get stripped. Am I missing something?
