我的用法是引导图标，复制您的SVG路径。

span{
    path{
        color: red;
    }
}

SVG引导的一个例子:

        <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="currentColor"
          class="bi bi-exclamation-octagon" viewBox="0 0 16 16">
          <path
            d="M4.54.146A.5.5 0 0 1 4.893 0h6.214a.5.5 0 0 1 .353.146l4.394 4.394a.5.5 0 0 1 .146.353v6.214a.5.5 0 0 1-.146.353l-4.394 4.394a.5.5 0 0 1-.353.146H4.893a.5.5 0 0 1-.353-.146L.146 11.46A.5.5 0 0 1 0 11.107V4.893a.5.5 0 0 1 .146-.353L4.54.146zM5.1 1 1 5.1v5.8L5.1 15h5.8l4.1-4.1V5.1L10.9 1H5.1z" />
          <path
            d="M7.002 11a1 1 0 1 1 2 0 1 1 0 0 1-2 0zM7.1 4.995a.905.905 0 1 1 1.8 0l-.35 3.507a.552.552 0 0 1-1.1 0L7.1 4.995z" />
        </svg>

为了更好地解决Manish Menaria的回答(非常感谢您的帮助)，请使用此过滤器生成器而不是专用生成器:https://angel-rs.github.io/css-color-filter-generator/

.filter-green{
    filter: invert(48%) sepia(79%) saturate(2476%) hue-rotate(86deg) brightness(118%) contrast(119%);
}

最简单的方法是使用https://icomoon.io/app/#/select之类的服务从SVG创建字体。上传你的SVG，点击“生成字体”，包括字体文件和CSS内容到你的侧，只是使用和样式它像任何其他文本。我总是这样使用它，因为它使造型更容易。

但正如@CodeMouse92评论的文章中提到的，图标字体会破坏屏幕阅读器(而且可能不利于SEO)。所以还是坚持使用svg吧。

一个很好的方法是使用mixin来控制笔画颜色和填充颜色。我的“svg”被用作图标。

@mixin icon($color, $hoverColor) {
    svg {
        fill: $color;

        circle, line, path {
            fill: $color
        }

        &:hover {
            fill: $hoverColor;

            circle, line, path {
                fill: $hoverColor;
            }
        }
    }
}

然后你可以在你的SCSS文件中执行以下操作:

.container {
    @include icon(white, blue);
}
