Improve our eMall platform responsiveness for mobile devices

We need some CSS and or HTML fixes to improve our system's responsivess and adaptability for mobile devices (smartphones & tablets). The system is based in Bootstrap 3 and a custom theme / skin on top of it. The applicant must propose CSS/HTML fixes for up to 10 distinct pages of the system. We expect the applicant to work remotely - not having any source code at hand - but using only standard Web browser tools such as Chrome inspect, to deliver the needed HTML/CSS fixes that will make our system better working for mobile devices. The system is here: [login to view URL] (you can switch to English using the dropdown in upper right part of the menu, but please try to use the Greek version since the content is mainly in Greek - just to have more meaningful pages as in below). The pages that need to be fixed are: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] and in addition up to five less important pages (so, up to 10 distinct web page templates) What we understand that needs fixing: - the site is more or less adequate for desktop devices - the site is not working / showing well in smartphones (Android / iOS) and tablets. For example, menus and navbars not hiding well using hamburger buttons when the resolution diminishes, multilevel drop downs not aligning well, boxes / cards with not aligned content (headings & paragraphs) etc - please tell us about the problems you see and can fix What we are expecting: - minor HTML fixes, mainly by using classes already included in the existing CSS. Please propose first standard Bootstrap CSS responsiveness fixes - if and only if needed, a new CSS to be injected into the system to improve the responsiveness i.e. the adaptability of the site to mobile devices How to win the project: - please tell us about the problems you see - propose a quick fix for any of these problems and send us the screenshots (before / after / the code you changed / brought in) Timeframe: - we would like to have the project delivered in 10 calendar days after its awarding
