Hello. For the website: [login to view URL] The accordeon slider with text and pictures schould look and work on way like this website works: [login to view URL] It schould look grafically and functionally pretty much the same. The biggest issues now are: 1. the slider sometimes works sometimes not (not stable at all, sometimes pictrures are appearing not horisontally but vertically), This is the biggest issue and musty be solved first!!! 2. the button that sends to next project( the button after the last slide) is not visible on all projects 3. On moble phone slider doesnt look as it schould. -Pictures sometimes not appearing or appearing vertically (basically the same problem as described in point 1), - the text, that's before the pictures is not shown, - the last button(as described in the point 3 is missing) The deadline is 6 july. So think good can you do it or not before applying for this job. Also another requirment: the point 1 MUST be fixed before 5 july. The budget for it is 40 dollars. We will create milestone for it. If its not gonnan be fixed before 5 july we not gonna pay anything!!! The total budget is 70 dollars!!!!! Who will help us? Thanx
