如何默认折叠文档属性/YAML/Properties/Metadata/Front Matter

可以试一下这个css代码

.metadata-properties:not(:hover) {
    visibility: hidden;
    float: right;
    max-width: 0px;
    max-height: 0px;
    z-index: 5;
}

.metadata-properties:not(:hover)::before {
    content: "✨"; 
    visibility: visible;
}

.metadata-properties {
    padding: 10px 20px;
    border-radius: 8px;
    border: none;
    background: none;
}
