将以下代码设置到webos设置–系统–全局代码里
<style>
/*桌面图标*/
.desktop>.desktopCont .dskApp {min-height: 100px;max-height: 100px;max-width: 80px;box-sizing: border-box;background: unset !important;justify-content: space-evenly !important;}
.desktop>.desktopCont .dskApp:hover,
.desktop>.desktopCont .dskApp.select{border-radius: 10px;backdrop-filter: blur(12px) saturate(0.9) brightness(1.2) opacity(0.9);}
.desktop>.desktopCont .dskApp.select {box-shadow: 0px 0px 5px -1px #ffffff80 inset;backdrop-filter: blur(12px) saturate(0.9) brightness(1.3) opacity(0.9);}
.desktop>.desktopCont .dskApp .appName{margin-top: 0px !important;width: 100% !important;-webkit-line-clamp: 2 !important; height:auto !important;}
.desktop>.desktopCont .dskApp.select>.uicon.dskIcon,
.desktop>.desktopCont .dskApp:hover>.uicon.dskIcon{transform: scale(1.2);}
/*.desktop>.desktopCont .dskApp.select{height: max-content !important;max-height: max-content;min-height: max-content;padding-top: 12px;padding-bottom: 5px;}
.desktop>.desktopCont .dskApp.select>.appName{margin-top: 12px !important;}*/
/*任务栏*/
.taskbar-component.taskbar{background:unset;}
.taskcont{display: flex;flex-direction: row;align-items: stretch;justify-content: center;}
.taskcont>.taskright {margin-left: 3px !important;position: relative !important;}
.taskcont>.taskright>.taskDate {font-size: 12px;justify-content: center;}
.taskcont>.tasksCont,
.taskcont>.tasksCont>.tsbar{width:auto !important;}
.taskcont>.tasksCont>.tsbar{margin-bottom: .25rem;margin-top: .25rem;}
.taskcont>.taskright>.handcr,
.taskcont>.taskright>.taskDate,
.taskcont>.tasksCont>.tsbar{background: var(--bg1);border-radius: 10px;backdrop-filter: blur(20px) saturate(1.2);}
.taskcont>.sidePane, .taskcont>.calnpane.dpShad{right:auto;}
.taskcont>.sidePane[data-hide=true]{right:0;}
</style>附上登录页的修改，设置–系统–底部代码
<style>
.fadeinScreen {top: calc(50vh - 266px) !important;}
/*,.fadeinScreen.login-form>div.text-xs.text-gray-400:last-child*/
.bottomInfo{bottom: 12px !important;font-size: 12px;color: rgb(255 255 255 / 50%) !important;}
.bottomInfo>span:last-child>a{line-height: normal !important;}
</style>当然也可以全局代码直接引入css文件，

全局代码如果资源管理器不需要放大，则增加一下样式
/*资源管理器*/
.webos-file-panel:not(.in-dragfile) .dskApp:hover {transform: none;}
.uicon img[data-click=true]:active, .uicon[data-pr=true]:active img {-webkit-transform: none;transform: none;}
全局代码，深色色彩调整
/*深色模式*/
body[data-theme=dark] .sidePane {--bg1: #2c333a;--bg2: #242424;--bg3: #343d42;--bg4: hsl(0deg 0% 100% / 5%);--sliderThumbClr: #3e5761;}
body[data-theme=dark] .hvlight.active {background: #00000060;}
body[data-theme=dark] .hvlight:hover {background: #00000080;}
