"位置:固定& quot;当父母有“转换"字样时，父母不会醒来CSS属性

问题描述

在我的项目中，我有一个屏幕，该屏幕应从屏幕的右侧放进去，因此我使用了 transform:translateX(100％)，然后将其更改为 transform:translateX(0％).它可以正常工作，可以达到缓解效果，但是在该屏幕上，我具有操作按钮，该按钮的css属性为 Position:Fixed; Bottom:0px; ，但这不起作用，我的意思是它不粘在屏幕底部.

这是我的JSfiddle: https://jsfiddle.net/sureshpattu/a1seze4x/

In my project I have screen which should ease-in from right side of the screen so for that thing I have used transform: translateX(100%) and then changing that to transform: translateX(0%). it works fine I able to achieve the ease-in effect but in that screen I have action button which has css property of Position: Fixed;Bottom: 0px; but this is not working I mean its not sticking in the bottom of the screen.

推荐答案

这不是错误.

看看规格:转换渲染模型

因此根据规范:具有固定位置的元素将相对于具有变换的元素-而不是视口

So according to the spec: the element with fixed positioning will become relative to the element with the transform - not the viewport

作为解决方法，您可以:

As a workaround you could:

1)使用过渡(例如，在 left 属性上)代替转换( translateX )

1) Use transitions (eg. on the left property) instead of transform (translateX)

2)从使用转换的容器中删除 position:fixed 按钮

2) Remove the position:fixed button from the container which uses transforms
