How to change the CSS to make the page display like the dialog shows?

PS,I think it's a way that to make the "left" div's height auto expand when the height of the "right" div or parent div expand, but I don't know how.

I have a very simple solution. Use css attribute display: table-cell; in .left{} & .right{} style like this:

    .left, .right { 

         display: table-cell;
         width:100px; 
         vertical-align:middle; 
         text-align:center;

     }

See the Demo: http://jsfiddle.net/rathoreahsan/qcCPG/3/

Here is different totally style that works:

.main{width:600px;border:1px solid red; height:auto; position:relative }
.main > div {display:inline-block; vertical-align:top; }
.main .left{background:lightblue; width:100px; height: 100%; }
.main .right{margin-left:5px; background:lightyellow; height: 100% }

You may want to go through this CSS tutorials at w3schools.

you can also use FLEX or combine FLEX with GRID

/******************************************
    1. FLEX
*******************************************/
.main{
    display: flex;
    flex-direction: row;
}
.left {
    width: 30%;
    align-self: center;
    text-align: center;
}
.right { 
    flex-grow: 1;
}
/******************************************
    2. FLEX with GRID
*******************************************/
.main{
    display: grid;
    grid-template-columns: 30% 1fr;
}
.left {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
}

have fun
