=================
contentEditable
Html中的contentEditable的属性可以打开某些元素的可编辑状态．也许你没用过contentEditable属性．甚至从未听说过．contentEditable的作用相当神奇．可以让div或整个网页，以及span等等元素设置为可写。
我们最常用的输入文本内容便是input与textarea 　使用contentEditable属性后，可以在div,table,p,span,body,等等很多元素中输入内容．
如果想要整个网页可编辑，请在body标签内设置contentEditable

 <div contentEditable id="topEditor">
                    <h2>
                        Comprehensive <br />HTML5/JavaScript framework <br />
                        for modern web and mobile app development
                    </h2>
</div>

IE中都有效，但chrome,firefox中input的contentEditable无效
=================
#cap {
                float: left;
                width: 242px;
                height: 225px;
                margin: 20px 30px 30px 0;
                background-image: url('../../content/web/dropdownlist/cap.png');
                background-repeat: no-repeat;
                background-color: transparent;
            }
            .black-cap {
                background-position: 0 0;
            }
            .grey-cap {
                background-position: 0 -225px;
            }
            .orange-cap {
                background-position: 0 -450px;
            }
            

function onChange() {
     var value = $("#color").val();
     $("#cap")
         .toggleClass("black-cap", value == 1)
         .toggleClass("orange-cap", value == 2)
         .toggleClass("grey-cap", value == 3);
 };

Text-Transform

 <div class="demo-section">
                <h2>Products</h2>
                <input id="products" style="width: 250px" />
            </div>


.demo-section h2 {
                    Text-Transform: Uppercase;
                    font-size: 1.2em;
                    margin-bottom: 10px;
                }
