I just discovered the magic of flex boxes (display: flex). Try this:



<style>

  #box {

    display: flex;

  }

  #b {

    flex-grow: 100;

    border: 1px solid green;

  }

</style>

<div id='box'>

 <div id='a'>Tree</div>

 <div id='b'>View</div>

</div>

Use the CSS Flexbox flex-grow property to achieve this.

html, body {

  height: 100%;

}

body {

  display: flex;

}

.second {

  flex-grow: 1;

}



<div style="background: #bef;">Tree</div>

<div class="second" style="background: #ff9;">View</div>

Use calc:

.leftSide {

  float: left;

  width: 50px;

  background-color: green;

}

.rightSide {

  float: left;

  width: calc(100% - 50px);

  background-color: red;

}

<div style="width:200px">

  <div class="leftSide">a</div>

  <div class="rightSide">b</div>

</div>
