Besides this version of Euclid's Elements located at http://aleph0.clarku.edu/~djoyce/java/elements/elements.html, there is the text of Heath's translation of Euclid's Elements on-line at
the Perseus Project at Tuft's University starting with the first definition of book I. Not just Heath's translation, but his commentary as well as the Greek text is available at the Perseus Project.
In 1847 Oliver Byrne designed a wonderful version of the Elements with an imaginative use of color to illustrate geometry. Bill Casselman has made Book I available at the University of British Columbia.
Another place you can get the statements of the propositions, but not their proofs is Richard Carr's
pages on Euclid's Elements.
