其实平时很少用到transform属性,一些放大缩小用width、height可以改变,一些位置变换,更是有margin,而一些旋转、2D、3D变换也不怎么能用得到。不过最近接触了一些图片的缩放,觉得不错,我就进行了一下学习。transform的元素会根据方法进行位置大小等的变换,但是还占据着原本在文档流中的位置。
呃……比想象的麻烦,主要是做了个界面。transform是前端做3D的基础,想要做得好,还是得费点心思的,这里只记录一下基本的用法吧。使用transform的时候兼容的写法如下所示,下文就直接使用transform。
.rotate_left1 { -ms-transform:rotate(7deg); /* IE 9 */ -moz-transform:rotate(7deg); /* Firefox */ -webkit-transform:rotate(7deg); /* Safari and Chrome */ -o-transform:rotate(7deg); /* Opera */ transform:rotate(7deg); }
1、matrix
matrix(n1,n2,n3,n4,n5,n6)和4*4矩阵matrix3d是变换图形的基本矩阵,学过图像处理的应该比较清楚,我懒得再仔细看了,毕竟这两个方法也不怎么常用到,使用后面的方法大概都可以解决大部分需求了,简单讲讲。
matrix(n1,n2,n3,n4,n5,n6)对应的是3*3矩阵(如下所示),只是其中的六个值,matrix的初始状态是matrix(1,0,0,1,0,0);
matrix3d()对应的4*4矩阵如下,它的初始状态是matrix3d(1,0,0,0,0,1,0,0,0,0,1,0,0,0,0,1)
2、none
初始状态,不做任何变换,对应着矩阵的单位矩阵
3、translate方法
进行位置的偏移,包括translate(x,y),translate3d(x,y),translateX(x),translateY(y),translateZ(z)。初始状态三个参数x,y,z都为0px,其正数分别为向右,下,靠近人的方向移动,因为我用的图片是在2D平面上的,其中z的偏移我看不出明显的区别,配合其他方法(如rotate应该可以看出来)。
.mydiv{ transform:translate(10px,-18px); }
.mydiv{ transform:translate3d(10px,-18px,28px); }
.mydiv{ transform:translateX(10px); }
.mydiv{ transform:translateY(-18px); }
.mydiv{ transform:translateZ(28px); }
4、scale
scale进行元素的缩放,包括scale(sx,sy), scale3d(sx,sy,sz), scaleX(sx), scaleY(sy), scaleZ(sz), 其中参数是原本长度的倍数,为1代表元素原本的大小。
.mydiv{ transform:scale(0.5,1.5); }
.mydiv{ transform:scale3d(0.5,1.5,1.2); }
.mydiv{ transform:scaleX(0.5); }
.mydiv{ transform:scaleY(1.5); }
.mydiv{ transform:scaleZ(1.2); }
5、rotate
围绕某个轴进行旋转,rotateX(x-angle)、rotateY(y-angle),rotateZ(z-angle),分别是围绕x轴,y轴,z轴进行指定度数(deg)的旋转,正数是顺时针方向旋转负数是逆时针,rotate是围绕z轴的旋转,rotate3d(x,y,z,angle)提供自定义旋转轴的方法,(x,y,z)就是表示在x、y、z坐标轴中的某一条轴,我看到的说法是0~1内的矢量值,但是经实验,其他数值也可以。
.mydiv{ transform:rotate(30deg); }
.mydiv{ transform:rotate3d(0.5,0.5,0.5,30deg); }
.mydiv{ transform:rotateX(30deg); }
.mydiv{ transform:rotateY(30deg); }
.mydiv{ transform:rotateZ(30deg); }
6、skew
skew进行倾斜,包括skew(x,y),skew(x),skew(y),有沿x轴,y轴方向倾斜两种方式,单位是deg。
.mydiv{ transform:skew(13deg,-12deg); }
.mydiv{ transform:skewX(13deg); }
.mydiv{ transform:skewY(-12deg); }
7、perspective
perspective(30px),这个说不太清楚,之前看到的解释也找不到网址了,大概它让元素在视觉上离你更近,配合其他变换才有效果。
补充:给父元素添加css--perspective:1000px;后,有关z的某些操作才会看得出来
总结:matrix和matrix3d包含了所有方法,但是没必要去做那么复杂的变换,需要了解具体变换的,文章matrix - matrix3d介绍中有介绍。需要实现3d效果,还是需要配合多种方法进行更加细致的调整,暂时不深入,还有就是可以配合动画和transition进行变换。
另附一个使用了vue.min.js,jquery和layui结合和所有变换方法的页面吧,所有时间都在弄这个上面了,比想象的复杂,相关的js、css用的是本地的,使用的是谷歌没怎么考虑兼容性的问题了
