2.input和textarea的区别?

是单行文本框。是多行文本框。</span></p></li></ul> <hr> <p><span style="font-size: 14px;">3.用一个p模拟textarea的实现？</span></p> <ul class=" list-paddingleft-2"> <li><p><span style="font-size: 14px;">首先我们需要知道p是高度自适应的，高度会随着内容的增加而增加。而textarea有着固定的大小，高度超过规定高度就会出现滚动条。</span></p></li> <li><p><span style="font-size: 14px;">p有一个属性叫做contenteditable，设置contenteditable属性为true就可以实现，p内容可编辑。</span></p></li> <li><p><span style="font-size: 14px;">实现了内容可编辑以后，在css中设置好规定的高度，设置overflow－y属性为auto,即可实现滚动条。</span></p></li> </ul> <hr> <p><span style="font-size: 14px;">4.移动设备忽略将页面中的数字识别为电话号码的方法?</span></p> <ul class=" list-paddingleft-2"> <li><p><span style="font-size: 14px;">移动设备中经常会出现将一串数字识别为电话的情况，数字的颜色和样式都会变化，点击可以直接拨打。</span></p></li> <li><p><span style="font-size: 14px;">添加如下代码可以关闭识别。</span></p></li> </ul> <div class="code" style="position:relative;
