canvas 大小设置



```html
<div class="imgbox">
      <img
        id="example1"
        :rel:animated_src="imgUrlGIF"
        rel:auto_play="0"
        width="367px"
        height="375"
      />
 </div>
  canvas{
    width: 648px !important;
    height: 300px !important;
    margin-left: 35px;
  }
  .imgbox {
    width:100%;
    height: 100%}

编辑器里有这个标签但是代码里没有，代码样式里写了大小但是不管用
