Custom CSS not working

Hi,

I am trying to use custom CSS for the title. I tried putting it into my custom .css skin file that I am loading via my theme as shown in the demo.

I also tried to put that CSS into the custom CSS box of the plugin.

The CSS is not applied and always overwritten by the fe-style.css
For example,
.grid-plus-container .post-item.thumbnail-title .post-info {
padding: 15px 0 0 0;
}

That is overwriting any chances I am trying to make in my custom CSS by changing that padding.

Thanks for the help !
