Add "scoped" attribute to the <style> tag , prevents its style from affecting other elements on the page

Add "scoped" attribute to the <style> tag , prevents its style from affecting other elements on the page

I also use the muse-ui UI framework to build my website.
I found that the style sheet in src/components/s-md-toolbar-left.vue changed the style of the Drawer component on the page.
So I added scoped-css-features to avoid this problem

给 <style> 标签添加了 scoped 属性 , 防止其样式影响页面上的其他元素

我也在使用 muse-ui 这个 UI 框架构建页面 .
我发现 src/components/s-md-toolbar-left.vue 中的样式表会改变页面内 Drawer 组件 .mu-item-wrapper .mu-item 的样式 .
添加了 scoped-css-features 来避免这个问题
