CSS background-size cover replacement for Mobile Safari

Question

Hi I have several divs on my page which have background images that I want to expand to cover the entire div which in turn can expand to fill the width of the viewport   Obviously background-size  cover behaves unexpectedly on iOS devices  I ve seen some examples of how to fix it  but I can t make them work in my situation  Ideally I d prefer not to add extra  lt img gt  tags to the HTML but if it s the only way then I will   Here is my code    x000D   x000D   section   x000D    margin  0 auto  x000D    position  relative  x000D    padding  0 0 320px 0  x000D    width  100   x000D    x000D   x000D   section1   x000D    background  url      50  0 no-repeat fixed  x000D    background-size  cover  x000D    x000D   x000D   section2   x000D    background  url      50  0 no-repeat fixed  x000D    background-size  cover  x000D    x000D   x000D   section3   x000D    background  url      50  0 no-repeat fixed  x000D    background-size  cover  x000D    x000D   lt body gt  x000D     lt div id  section1  class  section  gt  x000D          x000D     lt  div gt  x000D     lt div id  section2  class  section  gt  x000D          x000D     lt  div gt  x000D     lt div id  section3  class  section  gt  x000D          x000D     lt  div gt  x000D   lt  body gt  x000D   x000D   x000D    The question is  how can I get the background image to completely cover the section div  taking into account the variable width of the browser and the variable height of the content in the div

I found a working solution  the following CSS code example is targeting the iPad    media only screen and  min-device-width   768px  and  max-device-width   1024px         html             height  100           overflow  hidden          background  url  http   url com image jpg   no-repeat top center fixed          background-size  cover              body             height 100           overflow  scroll          -webkit-overflow-scrolling  touch             Reference link  https   www jotform com answers 565598-Page-background-image-scales-massively-when-form-viewed-on-iPad

There are answers over the net that try to solve this  however none of them functioned correctly for me  Goal  put a background image on the body and have background-size  cover  work mobile  without media queries  overflows  or hacky z-index  -1  position  absolute  overlays   Here is what I did to solve this  It works on Chrome on Android even when keyboard drawer is active  If someone wants to test iPhone that would be cool   body       background   FFFFFF url     image something jpg   no-repeat fixed top center      background-size  cover      -webkit-background-size  cover     safari may need this        Here is the magic  Treat html like a wrapper with a ratio enforced height relative to the actual viewport  You know the classic responsive tag  lt meta name  viewport  content  width device-width  initial-scale 1  gt   This is why the vh is used  Also  on the surface it would seem like body should get these rules  and it may look ok   until a change of height like when the keyboard opens up   html       height  100vh     set viewport constraint        min-height  100      enforce height

I have had a similar issue recently and realised that it s not due to background-size cover but background-attachment fixed   I solved the issue by using a media query for iPhone and setting background-attachment property to scroll   For my case    cover       background-size  cover      background-attachment  fixed      background-position  center center        media  max-width   iphone-screen            background-attachment  scroll            Edit  The code block is in LESS and assumes a pre-defined variable for  iphone-screen  Thanks for the notice  stephband

For Safari versions  lt 5 1 the css3 property background-size doesn t work  In such cases you need webkit   So you need to use -webkit-background-size attribute to specify the background-size   Hence use -webkit-background-size cover   Reference-Safari versions using webkit
