链接样式区分与美化 ​

Obsidian 默认的链接样式不够直观，内部链接、外部链接和未创建链接难以区分。通过 CSS 可以让不同类型的链接呈现不同样式。

链接类型区分 ​

css
/* 内部链接 - 紫色 */
.internal-link,
.cm-link {
  color: #7c3aed !important;
  text-decoration: none;
  border-bottom: 1px dashed transparent;
  transition: all 0.2s;
}

.internal-link:hover {
  border-bottom-color: #7c3aed;
  background: rgba(124, 58, 237, 0.05);
}

/* 外部链接 - 蓝色 + 外部图标 */
.external-link {
  color: #2563eb !important;
  text-decoration: none;
}

.external-link::after {
  content: ' ↗';
  font-size: 0.8em;
  opacity: 0.6;
}

.external-link:hover {
  color: #1d4ed8 !important;
  text-decoration: underline;
}

/* 未创建链接 - 灰色虚线 */
.is-unresolved,
.cm-hmd-internal-link .is-unresolved {
  color: #9ca3af !important;
  text-decoration: underline wavy;
  text-decoration-color: #9ca3af55;
  opacity: 0.7;
}

悬停动画 ​

下划线动画 ​

css
/* 链接下划线滑入动画 */
a.internal-link {
  position: relative;
  text-decoration: none;
}

a.internal-link::after {
  content: '';
  position: absolute;
  bottom: -2px;
  left: 0;
  width: 0;
  height: 2px;
  background: var(--interactive-accent);
  transition: width 0.3s ease;
}

a.internal-link:hover::after {
  width: 100%;
}

背景高亮 ​

css
/* 悬停背景高亮 */
.internal-link {
  border-radius: 3px;
  padding: 0 2px;
  transition: all 0.2s ease;
}

.internal-link:hover {
  background: rgba(124, 58, 237, 0.1);
  border-radius: 3px;
}

链接卡片化 ​

css
/* 外部链接卡片样式 */
a.external-link {
  display: inline-flex;
  align-items: center;
  background: linear-gradient(135deg, #667eea, #764ba2);
  color: white !important;
  padding: 2px 10px;
  border-radius: 6px;
  text-decoration: none;
  font-size: 0.9em;
  transition: transform 0.2s, box-shadow 0.2s;
}

a.external-link:hover {
  transform: translateY(-1px);
  box-shadow: 0 4px 12px rgba(102, 126, 234, 0.3);
}

链接预览样式 ​

css
/* 链接预览弹窗美化 */
.popover.hover-popover {
  border-radius: 8px;
  box-shadow: 0 8px 24px rgba(0, 0, 0, 0.12);
  border: 1px solid var(--background-modifier-border);
  max-width: 400px;
  max-height: 300px;
}

/* 预览内容 */
.popover.hover-popover .markdown-preview-view {
  padding: 12px 16px;
  font-size: 0.9em;
}
