是否可以使用SVG rect作为高度可变的HTML元素的边框

Question

我正在尝试使用SVG在HTML块周围创建一个具有固定宽度但高度灵活的点状边框。我很接近，但不能得到底部显示。

这里有一个小提琴（小提琴包含SVG图像，因此它可以内联URL编码元素，特别是#是%23)

SVG代码如下所示：

<svg width="300px" height="100%" xmlns="http://www.w3.org/2000/svg">
  <rect x="5" y="5" width="290" height="100%" 
    style="fill: yellow; fill-opacity: 0.5; stroke: #009fe3; stroke-width: 3; stroke-linecap: round; stroke-dasharray: 1 7"/>
</svg>

div.block {
  box-sizing: border-box;
  padding: 10px;
  width: 300px;
  background-image: url("dotted-border.svg");
}

我知道我可以添加另一个图像并使用CSS:after，但我很好奇！

为什么不使用直接的CSS边框呢？

div.block {
    box-sizing: border-box;
    padding: 10px;
    width: 300px;
    background-image: url("data:image/svg+xml;utf8,<svg width='300px' height='100%' xmlns='http://www.w3.org/2000/svg'><rect x='5' y='5' width='290' height='100%' style='fill: yellow; fill-opacity: 0.5; stroke: %23009fe3; stroke-width: 3; stroke-linecap: round; stroke-dasharray: 1 7'/></svg>");
}

div.block2 {
    box-sizing: border-box;
    padding: 4px;
    margin:3px;
    width: 294px;
    background-color:rgba(255,255,0,0.5);
    border:3px dotted #009fe3;
}

/* Alternative method using CSS3 border-image: */
div.block3 {
    box-sizing: border-box;
    padding: 4px;
    margin:3px;
    width: 294px;
    background-color:rgba(255,255,0,0.5);
    border:8px solid transparent;
    -webkit-border-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAAbklEQVR4nGL4W8zBMJAYmbMCiJ9C8Qosimkijyz5Hw2vQNNME3mYgqdYFDxFMoBm8oPGAQMeBQOeCAdFNhxwB4yWA6PlwGg5MODZcMAdMFoOjJYDo+XAgGfDAXfAaDkwWg6MlgMDggEAAAD//wMAIRKl6nQ6gLIAAAAASUVORK5CYII=) round;

    border-image-slice: 25%;
}
