Aligning 3 div tags inline
I have previously created and positioned divs "inline," beside one another (in Dreamweaver CS3). Suddenly, this past month, I find I am unable to create 3 divs side by side (the 2 outside divs smaller (200px@) and the center 300px SQ. I have not changed any settings that I am aware of. Still, I am completely unable to finish my home page to upload (after running checks). Can you please tell me the (Mac) settings I need to be aware of/and use to achieve this linear configuration? This problem exists within the container in a Dreamweaver document.
Thank you! James
