Add missing CSS resets for links

[Kikobeats]

Need to add minimal and common css reset style to ensure the look and feel works fine in each web integration.

Currently we are not adding this style:

text-decoration: none;
border: 0;
text-align: left;

Probably a better approach to handle that extracts all the reset in a file and call it when it is necessary, instead of polute the current implementation.
