How to remove Button border

[sunkan]

Hello, 

I would like to remove excess border on the container of my buttons, as i need them to be really small. 2 Narrow tiles. At this time they look like this, which cannot even be seen properly and it is also ugly.

Is there a way to fill all that white space with the button and to style it. 

Keep in mind that i am not able to change the theme or add anything in QMC or AMC.

I hope someone can help me.

Thanks
