Oh a jelly button & a css hack

Just wanting to show you all a ccs hack.
It use the combinaison of blur & contrast. You should wirte something like that :

.container{
  filter: contrast(20);
  background:white;
  .content1,.content2{
    filter:blur(0.5em);
    background:black;
  }
}

This will make the components a bit like sticky when they move close to each other. You can use it to make some nice loaders, or like that some button :
