如何使用CSS动画图像的某些部分? [英] How to animate some parts of an image using CSS?
问题描述
我有一张图片,我想用CSS动画部分内容。
I have an image and I want to animate some parts of it using CSS.
所以,我有一个问题:
- 我可以使用自动播放动画图像的某些部分吗?
我的意思是在一段时间后它应该动画自己而不重新加载整个页面。可能吗?
图片示例:
Image example:
带有24的磁盘必须从左边稍微呈圆形(如方向盘),文本小时应该从右边稍微出现圆圈就位,然后所有这一切都应该在1分钟或30秒内重复;)
The disk with 24 has to slightly appear rounding (like a wheel) from left, the text "hours" should slightly appear from right when the circle is in its place, then all this should repeat in 1 min or 30 seconds ;)
感谢您的帮助!
我希望如此。
I want it to be so.
推荐答案
仅使用单个HTML元素和CSS(以及可选的背景图像)
看起来像这些,但更顺畅!
- 带图像
Using only a single HTML element and CSS (and an optional background image)
It looks like these, but smoother!
- with images
- 没有图像(需要进一步的造型)
- with no images (further styling needed)
兼容性: IE10 +和所有现代浏览器。 Chrome目前需要 -webkit -
前缀。

内的文字隐藏为text-缩进:-9999px
显示的文本是用2 伪元素 h6
parent的子项,:在
和之前:
The text shown is created with 2 pseudo element children of the h6
parent, :before
and :after
伪元素子元素由于溢出:隐藏
和左:100%
/ 权利,隐藏在父母之外101%
(额外百分之一隐藏边框边缘)
The pseudo element children are hidden outside the parent thanks to overflow: hidden

10%时24文字旋转180度
At 10% the "24" text is rotated 180 degrees
25%到95%24和小时文字被移动到 tran的中心sform:translateX
At 25% to 95% the "24" and "hours" text is moved to the centre with transform: translateX
在100%时,文本会以转换回到境外:translateX(0)
和24推出 rotate(180deg)
At 100% the text is moved back outside with transform: translateX(0)
and the "24" is rolled out with rotate(180deg)
