[英]CSS3: How to rotate and scale an img at the same time?
I'm very confused.我很困惑。 Why can't I use scale and rotate at the same time?
为什么不能同时使用缩放和旋转? I've tried this, but it does not work:
我试过这个,但它不起作用:
.rotate-img{
-webkit-transform:scale(2,2);
-webkit-transform:rotate(90deg);
margin-left:20%;
margin-top:10%;
}
I tried jQuery, but does not work neither:我试过 jQuery,但也不起作用:
<style>
.zoom{
-webkit-transform:scale(2,2);
margin-left:20%;
margin-top:10%;
}
</style>
<script>
$(document).ready(function(){
$("img").dblclick(function(){
$(this).addClass("zoom");
$(this).contextmenu(function(){
$(this).css("-webkit-transform","rotate(90deg)");
return false;
})
});
})
</script>
How could I scale an img and when I clic the right click then rotate 90 deg.我怎么能缩放一个 img,当我点击右键然后旋转 90 度。
You can rotate an image with CSS using the transform
property with a rotate(**deg)
value您可以使用带有
rotate(**deg)
值的transform
属性使用 CSS 旋转图像
.rotate-img { -webkit-transform : rotate(90deg) scale(0.2); /* Chrome, Opera 15+, Safari 3.1+ */ -ms-transform : rotate(90deg) scale(0.2); /* IE 9 */ transform : rotate(90deg) scale(0.2); /* Firefox 16+, IE 10+, Opera */ left : -200px; position: relative; }
<img class="rotate-img" src="https://appharbor.com/assets/images/stackoverflow-logo.png" />
When applying transform
on multiple lines, it's like any other CSS property, and it gets overwritten so only the last line is used, just like with something like :在多行上应用
transform
时,它就像任何其他 CSS 属性一样,它会被覆盖,因此只使用最后一行,就像这样:
.myclass {
top: 100px;
top: 400px;
}
only the last one would apply, so you'll need to put all the transformations in one transform
.只有最后一个适用,因此您需要将所有转换放在一个
transform
。
Well, building on top of adeneo's answer, one that includes all browers capable of CSS transform .好吧,建立在 adeneo 的答案之上,其中包括所有能够进行CSS 转换的浏览器。
.rotate-img {
-webkit-transform: rotate(90deg) scale(2.2); /* Chrome 4+, Op 15+, Saf 3.1, iOS Saf 3.2+ */
-moz-transform: rotate(90deg) scale(2.2); /* Fx 3.5-15 */
-ms-transform: rotate(90deg) scale(2.2); /* IE 9 */
-o-transform: rotate(90deg) scale(2.2); /* Op 10.5-12 */
transform: rotate(90deg) scale(2.2); /* Fx 16+, IE 10+ */
margin: 10% 0 0 20%;
}
You do not need to write code separately to use both rotate and scale u can use it look like this :你不需要单独编写代码来使用旋转和缩放你可以像这样使用它:
transform: scale(1.3) rotate(7deg);变换:缩放(1.3)旋转(7度);
You can scale & rotate at the same time, but you HAVE to do it on the same line, otherwise you overwrite the prievius value with the new value.您可以同时缩放和旋转,但必须在同一行上进行,否则您会用新值覆盖 prievius 值。
let htmlElement = document.getElementById("rotate-img"); let scaleX = -0.3; let scaleY = 0.2; let angle = 45 ; // NOTICE!! THE BACK-TICKS, not regular quotes. Will decode variables inside before printing. // Code for Safari htmlElement.style.WebkitTransform = `scale( ${scaleX}, ${scaleY} ) rotate( ${angle}deg )`; // Code for IE9 htmlElement.style.msTransform = `scale( ${scaleX}, ${scaleY} ) rotate( ${angle}deg )`; // Standard syntax htmlElement.style.transform = `scale( ${scaleX}, ${scaleY} ) rotate( ${angle}deg )`;
<img id="rotate-img" src="https://appharbor.com/assets/images/stackoverflow-logo.png" />
Also notice that any already existing style on that element will be overwritten, unless you save that style into a (string-)variable first & add (append or concatenate) the new styles to that saved variable & then add the whole variable back onto the html-element.另请注意,该元素上任何已存在的样式都将被覆盖,除非您先将该样式保存到(字符串)变量中并将新样式添加(附加或连接)到该保存的变量中,然后将整个变量添加回html 元素。
