It is nice that this theme offers features as creating a excerpt from a page where it is linked to. With the builtin functionality it is not very nice to see a rather ugly alignment of the boxes.
What I now need to do is creating a manual excerpt and checking the result whether this aligns as desired. This takes a lot of effort which could be avoided with better coding.
I believe now that the .more-link CSS is not the right place to get the change done, it probably should have been in the level above (“grid”)? Unfortunately do I not have sufficient knowledge to get this implemented.
