The article also offers CSS implementation solutions and browser compatibility analysis to help developers choose the most appropriate implementation method based on specific requirements.
Overview of HTML Middle Dot Character
In web development, the middle dot character serves as a commonly used separator for horizontally dividing list items or other content elements. Unlike the period at the end of sentences, the middle dot character is vertically centered on the text baseline, providing better visual balance and aesthetics.
Core HTML Entity Representations
HTML provides multiple ways to represent the middle dot character, with · being the most commonly used entity. The primary implementation methods are:
<!-- Using named entity -->
<p>Item 1 · Item 2 · Item 3</p>
<!-- Using decimal numeric reference -->
<p>Item 1 · Item 2 · Item 3</p>
<!-- Using hexadecimal numeric reference -->
<p>Item 1 · Item 2 · Item 3</p>All three methods render the same middle dot character "·" in browsers, corresponding to Unicode code point U+00B7.
CSS Implementation Solutions
Beyond HTML entities, the middle dot character can also be inserted via CSS:
<style>
.separator::after {
content: "\00B7";
margin: 0 8px;
}
</style>
<span class="item">Item 1</span>
<span class="separator"></span>
<span class="item">Item 2</span>This approach is particularly useful for scenarios requiring CSS-controlled styling and spacing.

•or•- Typically slightly larger than the middle dot - Greek Ano Teleia:
