  <p>So my problem is that I do not know how to organize blocks in rows, because some blocks must have difeerent height, for example height of block 5. should have the same size as blocks 3. and 2. together.</p>
  
  <p>Is that even possible? Also there should be some space between blocks, so background image should fill those space.</p>
  
  <p>Please help me out.</p>
