代码块美化 ​

代码块是技术笔记的核心元素。通过 CSS 可以美化行内代码、代码块容器，提升代码可读性。

行内代码 ​

css
/* 行内代码样式 */
.cm-inline-code,
.markdown-preview-view code:not(pre code) {
  background-color: rgba(124, 58, 237, 0.1);
  color: #7c3aed;
  padding: 2px 6px;
  border-radius: 4px;
  font-family: 'JetBrains Mono', 'Fira Code', monospace;
  font-size: 0.9em;
}

/* 深色模式 */
.theme-dark .cm-inline-code,
.theme-dark .markdown-preview-view code:not(pre code) {
  background-color: rgba(124, 58, 237, 0.2);
  color: #a78bfa;
}

代码块容器 ​

css
/* 代码块容器 */
.markdown-preview-view pre,
.markdown-source-view .HyperMD-codeblock {
  background-color: #1e1e2e;
  border-radius: 8px;
  padding: 1em;
  margin: 1em 0;
  overflow-x: auto;
  border: 1px solid rgba(255, 255, 255, 0.05);
}

/* 代码块内文字 */
.markdown-preview-view pre code,
.cm-hmd-codeblock {
  font-family: 'JetBrains Mono', 'Fira Code', monospace;
  font-size: 14px;
  line-height: 1.6;
  color: #cdd6f4;
}

/* 深色模式 */
.theme-dark .markdown-preview-view pre {
  background-color: #11111b;
}

代码块标题 ​

css
/* 代码块语言标签 */
pre[class*="language-"]::before {
  content: attr(data-lang);
  display: block;
  font-size: 0.75em;
  color: var(--text-muted);
  margin-bottom: 8px;
  text-transform: uppercase;
  letter-spacing: 0.05em;
  font-family: 'JetBrains Mono', monospace;
}

复制按钮 ​

css
/* 代码块右上角复制提示 */
.markdown-preview-view pre {
  position: relative;
}

.markdown-preview-view pre:hover::after {
  content: '点击复制';
  position: absolute;
  top: 8px;
  right: 8px;
  font-size: 0.75em;
  color: var(--text-muted);
  background: var(--background-secondary);
  padding: 2px 8px;
  border-radius: 4px;
  opacity: 0.7;
}

语法高亮增强 ​

css
/* 关键字 */
.cm-keyword, .token.keyword { color: #cba6f7; font-weight: 500; }
/* 字符串 */
.cm-string, .token.string { color: #a6e3a1; }
/* 数字 */
.cm-number, .token.number { color: #fab387; }
/* 注释 */
.cm-comment, .token.comment { color: #6c7086; font-style: italic; }
/* 函数 */
.cm-def, .token.function { color: #89b4fa; }
/* 变量 */
.cm-variable, .token.variable { color: #f38ba8; }
/* 类型 */
.cm-type, .token.type { color: #f9e2af; }

行号显示 ​

css
/* 代码行号 */
.markdown-preview-view pre code {
  counter-reset: line;
}

.markdown-preview-view pre code > span {
  counter-increment: line;
}

.markdown-preview-view pre code > span::before {
  content: counter(line);
  display: inline-block;
  width: 2rem;
  margin-right: 1rem;
  text-align: right;
  color: #6c7086;
  font-size: 0.85em;
}
