This document summarizes common web vulnerabilities including cross-site scripting (XSS), cross-site request forgery (CSRF), and clickjacking. It provides examples of how each vulnerability can be exploited, such as using JavaScript to steal cookies or make unauthorized requests. The document also lists recommendations for preventing these issues, like validating and sanitizing input, using anti-CSRF tokens, and disabling JavaScript for sensitive pages. Resources for further reading on each topic are included.
This document discusses slideshow implementations using JavaScript and CSS3. It covers HTML structure, utilities like automatic playback and image lazy loading, different transition effects like fade and slide, design patterns like adapter and factory, and extending the switchable component. It also mentions alternatives using CSS3 transitions directly and addresses past memory leak issues in YUI.
