How Can CSS Create Nested Ordered Lists with Numbering Like 1.1, 1.2, 1.3?

Ordered Lists with Nested Numbering

Can CSS produce ordered list items that appear as 1.1, 1.2, 1.3 instead of the default 1, 2, 3 sequence?

Solution Using Counters

To achieve this result, you can harness the power of CSS counters:

OL { counter-reset: item }
LI { display: block }
LI:before { content: counters(item, ".") " "; counter-increment: item }

The above style sheet initializes a counter called item for each

    element. The
  1. elements are set to display as blocks, and a pseudo-element :before is added to each
  2. to display the counter value followed by a period and a space. The counter-increment property increments the counter for each
  3. element.

    Example

    <ol>
  <li>li element
    <ol>
      <li>sub li element</li>
      <li>sub li element</li>
      <li>sub li element</li>
    </ol>
  </li>
  <li>li element</li>
  <li>li element
    <ol>
      <li>sub li element</li>
      <li>sub li element</li>
      <li>sub li element</li>
    </ol>
  </li>
</ol>

    With the applied CSS, this HTML will render the list items with nested numbering as desired:

      1. li element
      2. 1.1. sub li element
      3. 1.2. sub li element
      4. 1.3. sub li element
      1. li element
      1. li element
      2. 3.1. sub li element
      3. 3.2. sub li element
      4. 3.3. sub li element

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
