ordered list

An ordered list in HTML is a list of items that are numbered, typically using the "ol" tag. Each item in the list is represented by the "li" tag. Here is an example of an ordered list in HTML:

<ol>
 <li>Item 1</li>
 <li>Item 2</li>
 <li>Item 3</li>
</ol>

This will create a numbered list with the items "Item 1", "Item 2", and "Item 3".

CSS (Cascading Style Sheets) is used to control the presentation of the HTML elements on a web page. You can use CSS to change the appearance of the ordered list, such as the font size or color. Here is an example of how you can change the font size of the list items in an ordered list:

<ol>
 <li style="font-size: 20px;">Item 1</li>
 <li style="font-size: 20px;">Item 2</li>
 <li style="font-size: 20px;">Item 3</li>
</ol>

This will set the font size of the list items to 20px. You can also use classes or ID's to select the elements, which is more efficient and maintainable.

<style>
.large-font{
 font-size:20px;
}
</style>
<ol>
 <li class="large-font">Item 1</li>
 <li class="large-font">Item 2</li>
 <li class="large-font">Item 3</li>
</ol>

This way you can easily change the font size for all elements with class large-font in one place.
