Two floated columns - one fixed, one loose width

Question

I\'ve looked around SO, but I cannot find one that matches my occurrence, I basically have two columns one fixed width (185px) and the other column has no fixed wid

Answer 1

Edited the solution, this time using flexbox, made the left column fixed using flex: 185px 0 0; then made the right column auto grow using flex-grow:1

*{
  box-sizing: border-box;
}

body{
  padding:0;
  margin:0;
}

#container{
  display:flex;
}

#left{
  height: 100vh;
  flex: 185px 0 0;
  background-color:tomato;
}

#right{
  flex-grow: 1;
}

#right > div{
  background:pink;
}

  
    

      
 Left 
      

        

        Right
