How to find the unclosed div tag [closed]

I made an online tool called Unclosed Tag Finder which will do what you need.

Paste in your HTML, and it will give you output like "Closing tag on line 188 does not match open tag on line 62."

Update: The new location of the Unclosed Tag Finder is https://jonaquino.blogspot.com/2013/05/unclosed-tag-finder.html

As stated already, running your code through the W3C Validator is great but if your page is complex, you still may not know exactly where to find the open div.

I like using tabs to indent my code. It keeps it visually organized so that these issues are easier to find, children, siblings, parents, etc... they'll appear more obvious.

EDIT: Also, I'll use a few HTML comments to mark closing tags in the complex areas. I keep these to a minimum for neatness.

<body>

    <div>
        Main Content

        <div>
            Div #1 content

            <div>
               Child of div #1

               <div>
                   Child of child of div #1
               </div><!--// close of child of child of div #1 //-->
            </div><!--// close of child of div #1 //-->
        </div><!--// close of div #1 //-->

        <div>
            Div #2 content
        </div>

        <div>
            Div #3 content
        </div>

    </div><!--// close of Main Content div //-->

</body>
