    We can add the following to a particular tag in CSS:

    -webkit-transform: rotate(90deg);
    -moz-transform: rotate(90deg);
    -o-transform: rotate(90deg);
    -ms-transform: rotate(90deg);
    transform: rotate(90deg);
    

    In case of half rotation change 90 to 45.

    Use the css "rotate()" method:

    div {
      width: 100px;
      height: 100px;
      background-color: yellow;
      border: 1px solid black;
    }
    
    div#rotate{
      transform: rotate(90deg);
    }
    <div>
    normal div
    </div>
    <br>
    
    <div id="rotate">
    This div is rotated 90 degrees
    </div>

    Use following in your CSS

    div {
        -webkit-transform: rotate(90deg); /* Safari and Chrome */
        -moz-transform: rotate(90deg);   /* Firefox */
        -ms-transform: rotate(90deg);   /* IE 9 */
        -o-transform: rotate(90deg);   /* Opera */
        transform: rotate(90deg);
    }

    Use transform: rotate(90deg):

    #container_2 {
        border: 1px solid;
        padding: .5em;
        width: 5em;
        height: 5em;
        transition: .3s all;  /* rotate gradually instead of instantly */
    }
    
    #container_2:hover {
        -webkit-transform: rotate(90deg);  /* to support Safari and Android browser */
        -ms-transform: rotate(90deg);      /* to support IE 9 */
        transform: rotate(90deg);
    }
    <div id="container_2">This box should be rotated 90&deg; on hover.</div>

    Click "Run code snippet", then hover over the box to see the effect of the transform.

    Realistically, no other prefixed entries are needed. See Can I use CSS3 Transforms?

    You need CSS to achieve this, e.g.:

    #container_2 {
        -webkit-transform: rotate(90deg);
        -moz-transform: rotate(90deg);
        -o-transform: rotate(90deg);
        -ms-transform: rotate(90deg);
        transform: rotate(90deg);
    }
    

    Demo:

    #container_2 {
      width: 100px;
      height: 100px;
      border: 1px solid red;
      -webkit-transform: rotate(45deg);
      -moz-transform: rotate(45deg);
      -o-transform: rotate(45deg);
      -ms-transform: rotate(45deg);
      transform: rotate(45deg);
    }
    <div id="container_2"></div>

    (There's 45 degrees rotation in the demo, so you can see the effect)

    Note: The -o- and -moz- prefixes are no longer relevant and probably not required. IE9 requires -ms- and Safari and the Android browser require -webkit-


    Update 2018: Vendor prefixes are not needed anymore. Only transform is sufficient. (thanks @rinogo)
