After updating to CC 1.4.0.2 I regenerated the HTML and CSS and suddenly parts of my layout are broken. As I dug into it I realized that the images in Inner Blocks all have the same default class name and now the individual styles overwrite each other:
I don’t understand why this effect didn’t show before regeneration?! But maybe this has also something todo with the problems I described above.
What I do is, I copy the whole component with the image in an inner block and change the styling. This worked until regeneration when I activated the class in the image as described earlier.
