You can include HTML like your example above in a WordPress.com blog if you add it in a text widget

Here is the text widget help page:

If you need any help getting that widget added, just post back here and I'll see what I can do to help.

Above is the link, as given here: http://www.bloglovin.com/en/widgets

The bloglovin' widgets are quire common, maybe just on blogger or tumblr sites. I would like a theme that allows different widgets, is simple, can be cutomised easily. I would love to make my site look exactly like I want it to look but I unfortunately don't know anything about coding etc.

Is not having the bloglovin widget a deal breaker? I'd be interested to hear your thoughts.

This is the first time I've seen a request for the bloglovin widget. I can add it to our requested widgets so it gets considered in the future, but it doesn't look like very many people have shown interest in it so far. Do you have a link for the widget you were thinking of?

I would like to add in a bloglovin widget to the sidebar but this theme seems to only allow selected widgets.

How can I do this?
