Begin ordered list from 0 in Markdown

Question

I\'m new to Markdown. I was writing something like:

#Table of Contents  
0. Item 0  
1. Item 1  
2. Item 2

But that generates:

Answer 1

Via html: use <ol start="0">

Via CSS:

ol {
    counter-reset: num -1; // reset counter to -1 (any var name is possible)
}
ol li {
    list-style-type: none; // remove default numbers
}
ol li:before {
    counter-increment: num; // increment counter
    content: counter(num) ". "; 
}

FIDDLE

Answer 2

Simply: NO

Longer: YES, BUT

When you create ordered list in Markdown it is parsed to HTML ordered list, i.e.:

# Table of Contents

0. Item 0  
1. Item 1  
2. Item 2

Will create:

<h1>Table of Contents</h1>
<ol>
  <li>Item 0</li>
  <li>Item 1</li>
  <li>Item 2</li>
</ol>

So as you can see, there is no data about starting number. If you want to start at certain number, unfortunately, you have to use pure HTML and write:

<ol start="0">
  <li>Item 0</li>
  <li>Item 1</li>
  <li>Item 2</li>
</ol>

Answer 3

You can use HTML start tag:

<ol start="0">
  <li> item 1</li>
  <li> item 2</li>
  <li> item 3</li>
</ol>

It's currently supported in all browsers: Internet Explorer 5.5+, Firefox 1+, Safari 1.3+, Opera 9.2+, Chrome 2+

Optionally you can use type tab for more sophisticated enumerating:

• type="1" - decimal (default style)
• type="a" - lower-alpha
• type="A" - upper-alpha
• type="i" - lower-roman
• type="I" - upper-roman

Answer 4

Update: Depends on the implementation.

The current version of CommonMark requires the start attribute. Some implementations already support this, e.g. pandoc and markdown-it. For more details see babelmark.
