If HTML is just markup then it is as good a format for resume as any other, rather better. Why? Because you can have the same content shown in various formats, content remaining the same, using CSS. It also gets very flexible since some areas can be commented out as per our job application.
Here I am dispalying two format of my resume, print preview format and web format using the same HTML document, when accessed from the browser. The changes were incorporated thought CSS tricks. (The CSS is included in the source.)
My Resume is available in the Menu under ‘About Me’. or here http://satishviswanathan.com/resume.html .
Format copied and modified from Charles H Ying’s available at http://www.satine.org/resume/. Thanks Charles, I really loved your concept.
