Convert 3 simple powerpoint slides into html/css coding (for a website)

The powerpoint slides are consists of:

1) 3 boxes comparing different levels of services, with texts, small icons (in jpeg), and shapes from powerpoint.

2) a simple flowchart (text boxes and arrows)

3) a table with about 15 rows and 4 columns

I need these to be turned into html / css codes so I can put them on a web page.

I may need to change the colours, font (incl. size) used later. So please code it so its easy to change.
