1.行内元素不能设置纵向的padding,margin
```
3. 鼠标移入后，图形缩放的算法
[].forEach.call(oC3div, function (item, index, array) {
item.onmouseenter = function () {
var margintop = 168;
timer = setInterval(function () {
margintop -= 5;
if (margintop <= 0) {
margintop = 0;
clearInterval(timer);
}
item.children[0].style.marginTop = margintop + "px";
}, 20)
}
})
4.鼠标点击盒子后，给相应的盒子添加css 样式名
for (var i = 0; i < oImgs.length; i++) {
oImgs[i].index = i;
oImgs[i].onclick = function () {
for(var i=0;i<oImgs.length;i++)
{
if(oImgs[i]==this)
{
this.className = "selected";
oImgc[this.index].className = "active";
}
else{
oImgs[i].className="";
oImgc[i].className="";
}
}
}
}
5. this.className = "selected";
$(this).siblings().attr("class","");
oImgc[this.index].className = "active";
$(oImgc[this.index]).siblings().attr("class","");
```
