Help please deal with the positioning in the center. There is a block, the exact width of which is not known, is specified by the content. Along the edges should be framed by two pictures, they also have to move apart.
I used folates for merging and expanding, and it is impossible to level such a unit in the center.
It does not leave the feeling that something did wrong, it seems that it can be easier, but I can not find the right option.
