When creating websites, a designer must take into account that all browsers do not present HTML code in the same manner. There are at least three solutions to this problem: create separate versions of the site for each browser; gear the site to one browser and recommend that users view it in that browser; or use a newer design method of XHTML and CSS. Based on the readings so far, it appears using XHTML and CSS is the best solution.
