img src SVG用CSS改变样式

html

<img src="logo.svg" alt="Logo" class="logo-img">

css

.logo-img path {
  fill: #000;
}

上面的svg加载并本机填充:#fff，但当我使用上面的css尝试将其更改为黑色时，它没有改变，这是我第一次使用svg，我不知道为什么它不工作。

在您的案例中，主要问题是您从<img>标记导入svg，该标记将隐藏svg结构。

您需要将<svg>标记与<use>结合使用以获得所需的效果。要使其工作，您需要在SVG文件<path id='myName'…>，然后能够从<use xlink:href="#myName"/>标签检索它们。 试试下面剪的。

.icon { display: inline-block; width: 2em; height: 2em; transition: .5s; fill: currentColor; stroke-width: 5; } .icon:hover { fill: rgba(255,255,255,0); stroke: black; stroke-width: 2; } .red { color: red; } .blue { color: blue; } <svg width="0" height="0"> <defs> <path id="home" d="M100 59.375l-18.75-18.75v-28.125h-12.5v15.625l-18.75-18.75-50 50v3.125h12.5v31.25h31.25v-18.75h12.5v18.75h31.25v-31.25h12.5z"/> </svg> <span class="icon red"> <svg viewbox="0 0 100 100"> <use xlink:href="#home"/> </svg> </span> <span class="icon blue"> <svg viewbox="0 0 100 100"> <use xlink:href="#home"/> </svg> </span>

注意，如果您想从外部源加载SVG(而不是将其嵌入到HTML中)，则可以将任何URL放在片段#之前。另外，通常不需要在CSS中指定填充。最好考虑在SVG本身中使用fill:"currentColor"。相应元素的CSS颜色值将被使用到位。

因此，您必须将SVG作为内联HTML使用。

说这是你的logo.svg代码(当你在textEditor上打开它):

Logo.SVG

<svg width="139" height="100" xmlns="http://www.w3.org/2000/svg">
    <!-- Note that I've Added Class Attribute 'logo-img' Here -->
    <g transform="translate(-22 -45)" fill="none" fill-rule="evenodd">
        <path
            d="M158.023 48.118a7.625 7.625 0 01-.266 10.78l-88.11 83.875a7.625 7.625 0 01-10.995-.5l-33.89-38.712a7.625 7.625 0 0111.475-10.045l28.653 32.73 82.353-78.394a7.625 7.625 0 0110.78.266z"
            fill="#00000" />
    </g>
</svg>

添加你想要的Class/ID到它(我添加了'logo-img'):

编辑Svg

<svg class="logo-img" width="139" height="100" xmlns="http://www.w3.org/2000/svg">
    <!-- Note that I've Added Class Attribute 'logo-img' Here -->
    ...
</svg>

现在应用你的Css规则:

CSS

.logo-img path {
   fill: #000;
}

Pro

通过这种方式，您可以对用户的操作(悬停，选中，…)进行动画化。

Con

你的HTML文件会一团糟。

这里是一个堆栈片段

<style> body { display: flex; justify-content: center; } .logo-img path { transition: .5s all linear; } .logo-img path { fill: coral; } .logo-img:hover path{ fill: darkblue; } </style> <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <svg class="logo-img" width="139" height="100" xmlns="http://www.w3.org/2000/svg"> <!-- Note that I've Added Class Attribute 'logo-img' Here --> <g transform="translate(-22 -45)" fill="none" fill-rule="evenodd"> <path d="M158.023 48.118a7.625 7.625 0 01-.266 10.78l-88.11 83.875a7.625 7.625 0 01-10.995-.5l-33.89-38.712a7.625 7.625 0 0111.475-10.045l28.653 32.73 82.353-78.394a7.625 7.625 0 0110.78.266z" fill="#00000" /> </g> </svg> </body> </html>

尝试纯CSS:

.logo-img {
  /* to black */
  filter: invert(1);
  /* or to blue */
  filter: invert(0.5) sepia(1) saturate(5) hue-rotate(175deg);
}

这对于想要使用CSS操作的PHP和.svg图像组合使用的人可能很有帮助。

你不能用CSS覆盖img标签内的属性。但是当svg源代码嵌入到HTML中时，你当然可以。我喜欢用require_once函数来解决这个问题，其中包含一个.svg.php文件。这就像导入一个图像，但你仍然可以用CSS覆盖样式!

首先包含svg文件:

<?php require_once( '/assets/images/my-icon.svg.php' ); ?>

它包括这个图标，例如:

<svg xmlns="http://www.w3.org/2000/svg" width="20.666" height="59.084" viewBox="0 0 20.666 59.084"><g transform="translate(-639.749 -3139)"><path d="M648.536,3173.876c0-2.875-1.725-3.8-3.471-3.8-1.683,0-3.49.9-3.49,3.8,0,3,1.786,3.8,3.49,3.8C646.811,3177.676,648.536,3176.769,648.536,3173.876Zm-3.471,2.341c-.883,0-1.437-.513-1.437-2.341,0-1.971.615-2.381,1.437-2.381.862,0,1.438.349,1.438,2.381,0,1.907-.616,2.339-1.438,2.339Z" fill="#142312"/><path d="M653.471,3170.076a1.565,1.565,0,0,0-1.416.9l-6.558,13.888h1.2a1.565,1.565,0,0,0,1.416-.9l6.559-13.887Z" fill="#142312"/><path d="M655.107,3177.263c-1.684,0-3.471.9-3.471,3.8,0,3,1.766,3.8,3.471,3.8,1.745,0,3.49-.9,3.49-3.8C658.6,3178.186,656.851,3177.263,655.107,3177.263Zm0,6.139c-.884,0-1.438-.514-1.438-2.34,0-1.972.617-2.381,1.438-2.381.862,0,1.437.349,1.437,2.381,0,1.909-.616,2.34-1.437,2.34Z" fill="#142312"/><path d="M656.263,3159.023l-1.49-14.063a1.35,1.35,0,0,0,.329-.293,1.319,1.319,0,0,0,.268-1.123l-.753-3.49a1.328,1.328,0,0,0-1.306-1.054h-6.448a1.336,1.336,0,0,0-1.311,1.068l-.71,3.493a1.344,1.344,0,0,0,.276,1.112,1.532,1.532,0,0,0,.283.262l-1.489,14.087c-1.7,1.727-4.153,4.871-4.153,8.638v28.924a1.339,1.339,0,0,0,1.168,1.49,1.357,1.357,0,0,0,.17.01h17.981a1.366,1.366,0,0,0,1.337-1.366v-29.059C660.414,3163.893,657.963,3160.749,656.263,3159.023Zm-8.307-17.349h4.274l.176.815H647.79Zm9.785,43.634v10.1H642.434v-17.253a4.728,4.728,0,0,1-2.028-4.284,4.661,4.661,0,0,1,2.028-4.215v-2c0-3.162,2.581-5.986,3.687-7.059a1.356,1.356,0,0,0,.4-.819l1.542-14.614H652.1l1.545,14.618a1.362,1.362,0,0,0,.4.819c1.109,1.072,3.688,3.9,3.688,7.059v9.153a5.457,5.457,0,0,1,0,8.5Z" fill="#142312"/></g></svg>

现在我们可以像这样用CSS简单地改变填充颜色:

svg path {
  fill: blue;
}

我首先尝试用file_get_contents()解决这个问题，但上面的解决方案要快得多。
