How to make a subject?
For example, the Google+ button code

&lt;g:plusone size=&quot;medium&quot;&gt;&lt;/g:plusone&gt;

Element g:plusone not allowed as child of element td in this context. (Suppressing further errors from this subtree.)
With Facebook in general —

&lt;iframe src=&quot;http://www.facebook.com/plugins/like.php?href=http://habrahabr.ru/& layout=standard&amp&show_faces=false&amp&width=450&amp&action=like&amp&colorscheme=light&amp&height=35&quot; scrolling=&quot;no&quot; frameborder=&quot;0&quot; style=&quot;border:none; overflow:hidden; width:450px; height:35px;&quot; allowTransparency=&quot;true&quot;&gt;&lt;/iframe&gt;<br/>

The validator ( validator.w3.org ) swears at all "&" characters - & did not start a character reference. (& probably should have been escaped as &.)

For the first one, you need to add a namespace:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:g="http://google.com/">

However, it seems that the namespace can be added directly to the element itself.
For the second, replace all & with &

I'm inserting social buttons into a page with JS. Because JS is still needed for the work of various social buttons, and they do not carry any useful information load, for example, for indexing.
