It is not changing because of all the inline-styles you got in there.
Did you try to copy-paste the following code instead of the one you are using?

As said bfore you may need to get rid of all the inline styles in your code for this to work.
You can remove
<span style="color: #000000;"> completely – Instead of
<a style="color: #000000; href="… it should just be
<a href="… and so on… it’s pretty easy to do.
