Image appears vertically

Hi,

I installed the plug-in for two of my websites.

For one it worked great, for the other, icons show vertically.

From what I read, it is because of the CSS of my theme which as a “display: block;” which is true.

Ok, but how can I solve the problem for this plugin without altering my theme CSS?

Please be clear ..ahah I am not CSS or WordPress expert.

Thank you for helping.
