I am happy to give you an interview or provide you with a consultation.
I am very interested in innovative ways to secure property and personal interactions: all the way from cryptography to user interfaces. I am not interested in trading, mining or building exchanges.

cee-ass-ass rule (before I forget)

1. Use divs with float:left/position:absolute and negative margins ONLY for the global page layout.

2. For inner modular things like “thumbnail with centered image and centered caption” NEVER EVER use layout tricks mentioned above. Always make sure the module does not require specific outer tags and styles. This is generally possible using tables.

Reasoning: when the smart object is inserted into unprepared environment (div or table) it is nearly impossible to put it into correct position since it has lost its height which should stretch outer container.
