我有一个我正在实现的菜单系统，它将为每个元素提供动画。我从Illustrator导出了SVG代码，我发现有一些潜在的优化领域。
有两层，彩色星星和彩色星星后面的白色星星。
菜单中的每颗星都是一样的，只是在不同的位置，顶层有不同的颜色。还有两个＆＃34;拱门＆＃34;这是完全相同的，只是定位不同。
SVG代码如下所示：

每个径向和线性渐变元素中的停止偏移是相同的，但是当我将它们添加为def并通过url＃引用它们时，定位关闭。我试过了：
<defs>
<linearGradient id="linearGradientOne" gradientUnits="userSpaceOnUse" x1="-7694.9893" y1="8409.7441" x2="-7694.9893" y2="7886.7349" gradientTransform="matrix(0.4687 0 0 0.4687 3758.0625 -3681.2319)">
<stop offset="0" style="stop-color:#FFFFFF;stop-opacity:0.4"/>
<stop offset="0.01" style="stop-color:#FFFFFF;stop-opacity:0.38"/>
<stop offset="0.06" style="stop-color:#FFFFFF;stop-opacity:0.27"/>

<stop offset="0.97" style="stop-color:#FFFFFF;stop-opacity:0.15"/>
<stop offset="1" style="stop-color:#FFFFFF;stop-opacity:0.2"/>
</linearGradient>
</defs>
<path opacity="0.46" fill="url(#linearGradientOne)" enable-background="new" d="M150.53,45.372V29.717

但定位是我不太了解的。我搜索了Google和Stack Overflow，发现了类似的问题，但没有一个能帮助我理解如何减少代码并优化SVG。
谢谢！
