Shipping Invoice increased font size is compressed

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.4.38

Hi, I would like to increase the size of my shipping invoice font size. I did this once before and it worked fine (on a site still current and running an older version of joomla and hikashop), but this time when I add:

<table width="100%" style="font-size: 25px">

to the Order / Invoice.php file, the font is compressed together and difficult to read. I need to fix this, as the shipping invoice is used as the postage text and attached to the goods when sent.

See image of compressed text (ShipingInv.png) vs the successful older version (GoodInv.png).

Also the date and inv number is off the edge and not readable, could this be moved over to the left a little?

Thanks for any help.

Hello,
Using a line-height CSS property will probably do the job .

Hi thanks for that. I've done a search but I can't find how to implement that code, could you give a little more detail and an example of how to use it and where it goes?

Also, is it possible to easily move the date and inv number over a little so it doesn't push off the edge of the screen?

Thanks.
