最短的bootstrap兼容方式，没有JavaScript:

.cameraicon {
    height: 1.6em; /* Set your own icon size */
    mask: url(/camera.svg); /* Path to your image */
   -webkit-mask: url(/camera.svg) no-repeat center;
}

像这样使用它:

<td class="text-center">
    <div class="bg-secondary cameraicon"/><!-- "bg-secondary" sets actual color of your icon -->
</td>

2022 Web组件<load-file>回答

这个(8行)原生Web组件加载外部内容，并将其注入DOM。

在一篇DEV博客文章中对此进行了解释和记录:<load-file> Web Component。

完整的源代码:

customElements.define("load-file", class extends HTMLElement { // declare default connectedCallback as sync so await can be used async connectedCallback( // call connectedCallback with parameter to *replace* SVG (of <load-file> persists) src = this.getAttribute("src"), // attach a shadowRoot if none exists (prevents displaying error when moving Nodes) // declare as parameter to save 4 Bytes: 'let ' shadowRoot = this.shadowRoot || this.attachShadow({mode:"open"}) ) { // load SVG file from src="" async, parse to text, add to shadowRoot.innerHTML shadowRoot.innerHTML = await (await fetch(src)).text() // append optional <tag [shadowRoot]> Elements from inside <load-svg> after parsed <svg> shadowRoot.append(...this.querySelectorAll("[shadowRoot]")) // if "replaceWith" attribute // then replace <load-svg> with loaded content <load-svg> // childNodes instead of children to include #textNodes also this.hasAttribute("replaceWith") && this.replaceWith(...shadowRoot.childNodes) } }) <load-file src="//load-file.github.io/heart.svg"> <!-- elements inside load-file are MOVED to shadowDOM --> <style shadowRoot> svg { height: 180px; /* Stack Overflow subwindow height */ } path:nth-child(2n+2) { fill: GREEN; /* shadowDOM style does NOT style global DOM */ } </style> </load-file>

我添加了一个测试页面-通过滤镜设置为SVG着色:

例如,

滤镜:反色(0.5)棕色(1)饱和(5)色相旋转(175度)

上传和着色您的SVG - Jsfiddle

我的想法来自:在图像标签SVGs上交换填充颜色

带有背景色的框元素上的SVG掩码将导致:

body{ overflow:hidden; } .icon { --size: 70px; display: inline-block; width: var(--size); height: var(--size); transition: .12s; -webkit-mask-size: cover; mask-size: cover; } .icon-bike { background: black; animation: 4s frames infinite linear; -webkit-mask-image: url(https://image.flaticon.com/icons/svg/89/89139.svg); mask-image: url(https://image.flaticon.com/icons/svg/89/89139.svg); } @keyframes frames { 0% { transform:translatex(100vw) } 25% { background: red; } 75% { background: lime; } 100% { transform:translatex(-100%) } } <i class="icon icon-bike" style="--size:150px"></i>

注意- Internet Explorer浏览器不支持SVG掩码

你不能用这种方法改变图像的颜色。如果将SVG作为图像加载，则无法在浏览器中使用CSS或JavaScript更改它的显示方式。

如果你想改变你的SVG图像，你必须使用<object>， <iframe>或使用< SVG > inline加载它。

如果希望使用页面中的技术，则需要Modernizr库，在该库中可以检查SVG支持，并有条件地显示或不显示备用图像。然后可以内联SVG并应用所需的样式。

See:

#time-3-icon { fill: green; } .my-svg-alternate { display: none; } .no-svg .my-svg-alternate { display: block; width: 100px; height: 100px; background-image: url(image.png); } <svg width="96px" height="96px" viewBox="0 0 512 512" enable-background="new 0 0 512 512" xml:space="preserve"> <path id="time-3-icon" d="M256,50C142.229,50,50,142.229,50,256c0,113.77,92.229,206,206,206c113.77,0,206-92.23,206-206 C462,142.229,369.77,50,256,50z M256,417c-88.977,0-161-72.008-161-161c0-88.979,72.008-161,161-161c88.977,0,161,72.007,161,161 C417,344.977,344.992,417,256,417z M382.816,265.785c1.711,0.297,2.961,1.781,2.961,3.518v0.093c0,1.72-1.223,3.188-2.914,3.505 c-37.093,6.938-124.97,21.35-134.613,21.35c-13.808,0-25-11.192-25-25c0-9.832,14.79-104.675,21.618-143.081 c0.274-1.542,1.615-2.669,3.181-2.669h0.008c1.709,0,3.164,1.243,3.431,2.932l18.933,119.904L382.816,265.785z"/> </svg> <image class="my-svg-alternate" width="96" height="96" src="ppngfallback.png" />

您可以内联SVG。用类名(my-svg-alternate)标记你的备份映像:

<svg width="96px" height="96px" viewBox="0 0 512 512" enable-background="new 0 0 512 512" xml:space="preserve">
<path id="time-3-icon" .../>
</svg>

<image class="my-svg-alternate" width="96" height="96" src="ppngfallback.png" />

在CSS中使用Modernizr (CDN: http://ajax.aspnetcdn.com/ajax/modernizr/modernizr-2.7.2.js)的no-svg类来检查SVG支持。如果没有任何SVG支持，SVG块将被忽略，图像将被显示，否则图像将从DOM树中删除(display: none):

.my-svg-alternate {
  display: none;
}
.no-svg .my-svg-alternate {
  display: block;
  width: 100px;
  height: 100px;
  background-image: url(image.png);
}

然后你可以改变你的内联元素的颜色:

#time-3-icon {
   fill: green;
}

这里是快速而愤怒的方式:)
