Cascading style sheets (CSS) can distinguish between design and content and can efficiently separate it which ultimately increases the accessibility of the web site. CSS is designed to make sites easily optimized for search engines. CSS is known for its simplicity and can easily update your website. By using CSS in an efficient way, a site can make it to the top of Google search results. While in case of Flash users mistook the idea of it. Flash was never meant to generate SEO as it was not designed for it. CSS is more accessible than Flash, online. So if you want be visible online or be on the top of search results, use CSS rather than Flash. But recent progress show that Adobe is working hard to make data and information available for search engines. There are still so many features in Flash that CSS does not have. It is now a saturation point for CSS and should allow Flash to take the lead. It is also known that the popular search engines Google and Yahoo are becoming more flash friendly by providing data and information regarding Flash files. Flash can display or change data without reloading or refreshing the page but in CSS you have to reload the page.  Flash has greater interactivity, control over CSS. Flash provides unlimited freedom to the designer as it allows adding animations etc to web pages. Regardless of the fonts installed in the user’s machine, flash allows to display the font in the website.
