Ok if you visit the web site , you will see some things stranges , first the header navigation bar ,you will see that it doesn’t have any effects , but It must contain a Jquery effect , but it doesn’t work , that’s the first thing
after that a problem with the slider it’s under the navigation , it must contain some photos but they don’t load at all , after that , the photos should have a smart load option , that allows to load images only in the viewport of the browser but also that doesn’t work , also if you open a topic you will see some thing strange , my post is that http://elsa7er.org/%D9%81%D8%A7%D9%8A%D8%B1%D9%81%D9%88%D9%83%D8%B3-10-%D8%A7%D9%84%D9%86%D8%B3%D8%AE%D8%A9-%D8%A7%D9%84%D9%86%D9%87%D8%A7%D8%A6%D9%8A%D8%A9-%D8%AC%D8%A7%D9%87%D8%B2%D8%A9-%D9%84%D9%84%D8%AA%D8%AD%D9%85/
