问题描述

这就是我想要的



我有:

#image1 {position :绝对; bottom:0px; align-self:auto; background-color:#dc022e;宽度:340px; height:100px;边界半径:50%/ 100%; border-bottom-left-radius:0; / * transform:rotate(10deg); * / border-bottom-right-radius:0;不透明度:0.8; }#image2 img {width:80%; }

< div> < div id =image2> < img src =http://t1.gstatic.com/images?q=tbn:ANd9GcThtVuIQ7CBYssbdwtzZjVLI_uw09SeLmyrxaRQEngnQAked5ZB> < / DIV> < div id =image1>< / div>< / div>

最后,我不知道如何让它旋转,并像图片一样切割边距。

解决方案

<一个快速的例子就是使用一个伪元素,并在后台设置图片。



  div {position:relative; height:300px;宽度:500px;背景:url(http://lorempixel.com/500/300); / *图片路径* / overflow:hidden; / *隐藏圆圈的其余部分* /} div:before {content:;位置:绝对; / *参照div * / top的位置:100%;剩下:50%;宽度:0; / *定义值,如果你不想悬停* / height:0;边界半径:50%;背景:番茄; / *可能是rgba值(你可以去除不透明度)* /不透明度:0.5; transform:translate(-50%,-50%); / *确保它位于图像的中心* / transition:全部为0.4s;} / * Demo Only * / div:hover:before {/ *声明删除悬停* /高度:100%; / *转换:旋转(-50%,-50%)旋转(5deg); / *确保它在图像的中心+旋转* /} div {/ *这是东西的文字* / font-size:40px; line-height:300px; text-align:center;}  

< div> HOVER ME< / div>


This is what i am trying to achive

i have :

    #image1 {
    position: absolute;
    bottom: 0px;
    align-self: auto;
    background-color: #dc022e;
    width: 340px;
    height: 100px;
    border-radius: 50% / 100%;
    border-bottom-left-radius: 0;
    /*transform: rotate(10deg);*/
    border-bottom-right-radius: 0;
    opacity: 0.8;
    }
    
    #image2 img {
    width: 80%;
    }

<div>
  <div id="image2">
    <img src="http://t1.gstatic.com/images?q=tbn:ANd9GcThtVuIQ7CBYssbdwtzZjVLI_uw09SeLmyrxaRQEngnQAked5ZB">
  </div>
  <div id="image1"></div>
</div>

Finally I don't know how to make it rotated and with the margins cut like in the picture

解决方案

A Quick example of this would use a pseudo element and have the image set in the background.

div {
  position: relative;
  height: 300px;
  width: 500px;
  background: url(http://lorempixel.com/500/300);/*image path*/
  overflow: hidden;/*hides the rest of the circle*/
}

div:before {
  content: "";
  position: absolute; /*positions with reference to div*/
  top: 100%;
  left: 50%;
  width: 0;/*define value if you didn't want hover*/
  height: 0;
  border-radius: 50%;
  background: tomato;/*could be rgba value (you can remove opacity then)*/
  opacity: 0.5;
  transform: translate(-50%, -50%);/*ensures it is in center of image*/
  transition: all 0.4s;
}


/*Demo Only*/
div:hover:before {/*place this in your pseudo declaration to remove the hover*/
  height: 100%;
  width: 150%;/*this makes the shape wider than square*/
  transform: translate(-50%, -50%) rotate(5deg);/*ensures it is in center of image + rotates*/
}
div {/*This stuff is for the text*/
  font-size: 40px;
  line-height: 300px;
  text-align: center;
}

<div>HOVER ME</div>
