Stone Colours in a row

[Rajastones]

Hello,

 

I have Prestashop 1.3

 

I have no idea about programming, but I need to know how to have my colour swatches all in a row.

 

If anyone could look at http://www.rajastones.co.uk/Basins/148-beige-sandstone-wash-basin.html

 

You can see the boxes are not in line. I have little programming experience and any assistance would be appreciated. I could make the colour blocks smaller, but I have gone through styles.css, global.css and products.tpl. I have attempted to use Firebug to trackdown the code, but I am not sure of where I should be looking.

 

Is there a basic guide on how to change elements in a website?

 

Any help would be appreciated.

 

Thanks
