How to customize numbered lists on Blogger.

List style means numeric serial that can be used in Blog post. Generally by default Blog has list style option where by selecting two or more line if we click on List option then it will automatically add the serial number per line.

You don't have to worry about adding the HTML, because the editor does it for you by using this tool. If you go to the HTML tab, you'll see that the list you created appears something like this:

<ol> <li>The content of the 1st. element</li>
<li>The content of the 2nd. element</li>
<li>The content of the 3rd. element</li>
<li>The content of the 4th. element</li>
etc... </ol>

This tool will automatically number each element of the list taking an "order", hence the name "ordered lists in HTML". In each element a number is successively generated (from 1 onewards), though you can not see this in the HTML code.

Using ordered lists in posts

Creating numbered lists is very suitable for giving any instructions. It is ideal for cooking blogs where the steps in a recipe has to be numbered, or in those blogs that share tutorials... but can be used in any type of blog that need to number something.

}

Customization: 

In blue are highlighted the values that can be edited in the CSS of these three examples, and added some comments highlighted in /* green */, so that you can know what each thing does.

 Compatibility:

This will work in all browsers including IE8 - in the case of Internet Explorer 7, the number' styles will not be seen as it does not support the :before or :after pseudo-elements. However, I have added a line in the CSS that's specific for that browser and will bring up the default numbering of the ordered list.
Hopefully this will be useful for you ;)
