跨浏览器方式通过Javascript / CSS翻转html /图像？

Question

Is there a library/simple way to flip an image?

Flip image like this:

AABBCC      CCBBAA
AABBCC  ->  CCBBAA

I'm not looking for animations , just flip the image.

I've googled to no avial and only found a complex version that utilized SVG on MozillaZine which I'm not confident that it'll work cross-browser.

Answer 1

The following CSS will work in IE and modern browsers that support CSS transforms. I included a vertical flip class just in case you might want to use it too.

.flip-horizontal {
    -moz-transform: scaleX(-1);
    -webkit-transform: scaleX(-1);
    -o-transform: scaleX(-1);
    transform: scaleX(-1);
    -ms-filter: fliph; /*IE*/
    filter: fliph;
}
.flip-vertical {
    -moz-transform: scaleY(-1);
    -webkit-transform: scaleY(-1);
    -o-transform: scaleY(-1);
    transform: scaleY(-1);
    -ms-filter: flipv; /*IE*/
    filter: flipv;
}

Take a look at one of the many reflection.js type libraries, They are pretty simple. In IE they will take and use the 'flipv' filter, there is a 'fliph' filter too. Inside of other browsers, it will create a canvas tag and use the drawImage. Although Elijah's answer probably supports the same browsers.

Answer 3

Just dug up this answer while trying to fix a bug, while the suggested answer is correct I have found that it breaks most modern CSS Linting rules regarding the inclusion of all vendor rules for the transform. However, including the -ms-tranform rule causes an odd bug in IE9 where it applies the filter and -ms-transform rules causing an image to flip and flip back again.

Here is my suggested improvement which also supports CSS Lint rules:

.flip-horizontal {
    -moz-transform: scaleX(-1);
    -webkit-transform: scaleX(-1);
    -o-transform: scaleX(-1);
    -ms-transform: scaleX(1); /* linting rule fix + IE9 fix */
    transform: scaleX(-1);
    -ms-filter: fliph;
    filter: fliph;
}
.flip-vertical {
    -moz-transform: scaleY(-1);
    -webkit-transform: scaleY(-1);
    -o-transform: scaleY(-1);
    -ms-transform: scaleY(1);  /* linting rule fix + IE9 fix */
    transform: scaleY(-1);
    -ms-filter: flipv;
    filter: flipv;
}

If you only want to flip a background image you can use the class on the internal elements inside a flipped div. Basically you're flipping the internal elements with the main div, but flipping each of them back. Works in Firefox anyway.

Like this:

<div id="container" class="flip-horizontal"> <!-- container would have your background image -->
<h3 class="flip-horizontal">Hello There!</h3>
<p class="flip-horizontal">Here is some text</p>
</div>
