Re: headings on hidden pics dont line up

[cybershot]

you are missing the closing </li> tags on all of your unordered lists. You have this

<ul>
<li>January
</ul>

Should be this

<ul>
<li>January</li>
</ul>

run your code through the validator

select the direct input tab, copy and paste your code into it and then start fixing the errors.
