1.前言,看过很多的轮播器代码;但是心中,老想着有没有简单的办法来实现同样的效果。搜到这个(下方链接),眼前一亮,便动手实践改进。主要工作,还是对文章第一段提出的“如果中间间隔有图片,那么在css3动画的执行过程中还是会看到,比较不给力”问题,进行改进,以及实现自动轮播。
不知道是哪位大神写出来的,也不知道后续有没有更新解决方案,总之,没搜到,于是,献丑贴代码吧。

使用html5+css3来实现slider切换效果告别javascript+css链接描述

2.源码链接里有,这里只说改变的地方,和自己写的代码。

  2.1 将CSS样式处,#slidebrs .inner处的过渡动画取出,改为新的animated类,代码

                margin-left: -100%;
            }
            
            #slider3:checked~ #sliders .inner {
                margin-left: -200%;
            }
            
            #slider4:checked~ #sliders .inner {
                margin-left: -300%;
            }
            
            #slider5:checked~ #sliders .inner {
                margin-left: -400%;
            }
也有其它有些小样式变化,比如,inner添加了cursor:pointer;
还在HTML中input标签全添加了hidden属性,用于隐藏一个小BUG,BUG结尾有说,但影响不大。

                }

            })

3.结语,小BUG就是,删除input标签的hidden属性;执行以下顺序,在input标签组上,若点击间隔为一个及以上,下一次点击相邻图片时,不会出现动画。 但是下方laber标签就没有这个BUG,没有去想。 匆匆结束,代码肯定也可以优化。
收获就是,深深认识到了CSS3中“~“选择符的厉害之处,以及laber input的灵活运用。

肯定还有其它解决思路,献丑,求抱大神大腿,求大神指点。
