No default, taken from page format

right - the div 'floats' on the right
Default - if this value is missing, the div is centered on the page

marginleft = the amount of space between the div and the text to the left of the div (particularly good to use when using float=right)
Default - if this value is missing, the page format is used

(particularly good to use when using float=left)
Default - if this value is missing, the page format is used

margintop = the amount of space to the line above the div
Default = 10px;

marginbottom = the amount of space to the line below the div
Default = 10px;

Button Formatting:

Image Classes:
The shortcode will add a 'placeholder' Paypal image that is 1px wide by 1px tall into the button. The code adds a class of "ppalholder" to this image.  This will allow site owners to add the class to their theme styles and remove any borders that cause the image to be 'visible'.

Class added to Buy Now, Add To Cart, Hosted or Subscribe button
The code will add the class "ppalbtn" to the actual image embedded on the page to allow for more formatting choices.

Sample Usage:

Buy Now Button:
[paypal type="paynow" amount="12.99" email="payments@arvoreentreasures.com" itemno="12345657" name="Description" noshipping="1" nonote="1" qty="1" shipping="4.00" shipping2="1.00" currencycode="USD" imageurl="https://www.paypal.com/en_US/i/btn/btn_paynowCC_LG.gif" rm="2" notifyurl="http://notifyurl.com" returnurl="http://returnurl.com" scriptcode="scriptcode" imagewidth="100px" pagestyle="paypal" lc="AU" cbt="Complete Your Purchase"]

Subscribe Button with 2 trial periods and recurring Monthly payments.
[paypal type="subscribe" email="payments@arvoreentreasures.com" itemno="12345657" name="Description" noshipping="1" currencycode="USD" imageurl="https://www.paypal.com/en_US/i/btn/btn_paynowCC_LG.gif" a1="1" p1="7" t1="D" a2="3" p2="1" t3="M" a3="47" p3="1" t3="M" rm="2" notifyurl="http://notifyurl.com" returnurl="http://returnurl.com" scriptcode="scriptcode" imagewidth="100px" pagestyle="paypal" lc="AU" cbt="Complete Your Purchase"]

Hosted Button
[paypal type="hosted" buttonid="1234456" imageurl="https://www.paypal.com/en_US/i/btn/btn_paynowCC_LG.gif"]

[paypal type="addtocart" amount="1.99" email="payments@arvoreentreasures.com" itemno="12345657" name="Description" noshipping="1" nonote="1" currencycode="USD" imageurl="https://www.paypalobjects.com/en_AU/i/btn/btn_cart_LG.gif" rm="2" notifyurl="http://notifyurl.com" returnurl="http://returnurl.com" scriptcode="scriptcode" cbt="Return to Me" cancelreturn="http://shoppingcartcancelurl.com" lc="AU" qty="4" shipping="3.00" shipping2="1.50" pagestyle="paypal"]

Adding formatting to Hosted Button
To use your own custom image hosted on your site, that is 200px wide, center the button in the line and leave 20px space above and 10px space below:
[paypal type="hosted" buttonid="1234456" imageurl="http://yourdomainname.com/images/buynow.jpg" imagewidth="200px" divwidth="200px" margintop="20px" marginbottom="10px"]

All formatting options work on three button types.
