Typically, unordered-list items are displayed with a bullet, which can be of several forms, like a dot, a circle, or a square. The bullet style is not defined in the HTML description of the page, but in its associated CSS, using the <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/list-style-type"><code>list-style-type</code></a> property.</li> <li>The <code><ul></code> and <a href="ol"><code><ol></code></a> elements may be nested as deeply as desired. Moreover, the nested lists may alternate between <code><ol></code> and <code><ul></code> without restriction.</li> <li>The <a href="ol"><code><ol></code></a> and <code><ul></code> elements both represent a list of items. They differ in that, with the <a href="ol"><code><ol></code></a> element, the order is meaningful. To determine which one to use, try changing the order of the list items; if the meaning is changed, the <a href="ol"><code><ol></code></a> element should be used, otherwise you can use
