Custom CSS support

[luftaquila]

Thank you for the great simple tool.

For those who want a custom CSS, you can include a <style> tag inside the markdown.

The best practice is to add a separate markdown style.md that has only style tag inside, and build it together like this:

npx --yes -- single-page-markdown-website index.md style.md --output .

For example, this is my style.md.

<style>
body, .top-bar, .menu {
  background-color: #f1f5f9 !important;
  color: rgb(51, 65, 85) !important;
}

h1, h2, h3, h4, h5 {
  color: #000!important;
}

@media (prefers-color-scheme: dark) {
  body, .top-bar, .menu {
    background-color: #0A0A0C !important;
    color: rgb(209, 213, 219) !important;
  }

  h1, h2, h3, h4, h5 {
    color: #fff !important;
  }
}

/* Thick title font */
.top-bar__title-link {
  font-weight: 600;
}

/* Hide h2 headers on topbar */
.top-bar__items ul:first-child {
  display: none;
}

/* Hide h1 header on sidebar */
.menu > ul:nth-child(2) > li > a,
.menu > ul:nth-child(2) > li li li li li a {
  display: none;
}

.menu li li a {
  padding-left: 1rem;
}

.menu li li li a {
  padding-left: 2rem;
}

.menu li li li li a {
  padding-left: 3rem;
}

/* Wider content width */
.content__inner {
  max-width: 80ch !important;
}

/* Add dot next to the number */
.content ol li:before {
  content: counter(count)'.' !important
}

/* Skip number increment on ul */
.content ul li {
  counter-increment: none;
}

/* Better bullet for li */
.content ul li:before {
  content: '◦' !important
}

/* Better margins for list */
.content ul, .content ol {
  margin-top: 0.5rem;
  margin-bottom: 0.5rem;
}

.content ul li, .content ol li {
  margin-left: 1.5rem;
  padding-left: 1rem;
}

.content li ul li, .content li ol li {
  margin-left: 0.5rem;
}

/* limit image width for vertical images */
.content img {
  max-height: 700px;
}

/* Slack style inline code block */
.content code {
  color: #e8912d !important;
}

/* Github style code block */
.content pre code {
  font-size: 0.9rem;
  line-height: 1.2rem;
  color: #ccc !important;
}

/* Same margin as outside details */
.content details,
.content details p {
  margin-top: 1rem;
}

/* Cursor pointer for details expand */
.content details summary {
  cursor: pointer;
  text-decoration: underline;
  text-decoration-thickness: 1px;
  text-underline-offset: 0.1875rem;
}

/* More margin at header bottom */
.content h1, .content h2, .content h3, .content h4 {
  margin-bottom: 1rem;
}

.content h5 {
  font-size: 0.9rem;
  font-style: italic;
}

/* Github style table */

  width: 100%;
  border-collapse: collapse;
  border-spacing: 0;
  background: #f1f5f9;
