Have you ever wanted to embed a Youtube video on a page AND have it validated? Youtube allow you to specify the size you want etc and then give you the code using the embed tag – so it looks like this:
<object width="480" height="295">
<param name="movie" value="http://www.youtube.com/v/n69yPQGcSJY&hl=en&fs=1&">
</param>
<param name="allowFullScreen" value="true">
</param>
<param name="allowscriptaccess" value="always">
</param>
<embed src="http://www.youtube.com/v/n69yPQGcSJY&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="295"></embed></object>
If you’re curious, it’s Gavin Bate talking about climbing Everest.
Anyway, the code won’t validate because you can’t use the embed tag. What works is the following:
<object type="application/x-shockwave-flash" style="width:480px; height:295px;" data="http://www.youtube.com/v/n69yPQGcSJY&hl=en&fs=1&rel=0">
<param name="movie" value="http://www.youtube.com/v/n69yPQGcSJY&hl=en&fs=1&rel=0" />
</object>
Notice, that I also added “amp;” to the &s.
My second tip is to do with blob lists inside blob lists, also referred to as nesting bullet points.
You might think that the correct way to code the following:
- Adam
- Eve
- Cain
- Abel
Was like this:
<ul>
<li>Adam></li>
<li>Eve</li>
<ul>
<li>Cain</li>
<li>Abel</li>
</ul>
</ul>
But that is invalid. It is correctly written as:
<ul>
<li>Adam></li>
<li>Eve
<ul>
<li>Cain</li>
<li>Abel</li>
</ul></li>
</ul>
And just talking about blob lists... You do know that you can control what type of blob you get. For example, code:
<ul type="square">
and you’ll get a square blob. You can also use “circle”. For ordered lists try lower or upper case Roman (“i” or “I”), and lower or upper case letters “a” or “A”).
