A comprehensive coverage of CSS is outside the scope of this book, but hopefully this chapter has provided necessary information for styling OpenLayers elements. More extensive information on CSS can be found at the W3Schools site, located at http://www.w3schools.com/css/default.asp.

A developer that has proficient design skills is not a common thing—fortunately, there are resources that provide high quality, professional user interface elements. GeoExt is a third party library that integrates ExtJS, a popular JavaScript framework, with OpenLayers, and includes numerous user interface and OpenLayers map components. It does, however, require a bit of familiarity with the ExtJS library. GeoExt can be found at http://www.geoext.org/index.html , and the ExtJS can be found at http://www.sencha.com/products/js/.
