css - Why Parallax effect doesn't work on mobile devices? -


i working laravel 5.4 application having parallax effect main background. works fine on desktop, , works perfect on varied screen size through developer tool, when same page accessed via mobile device, parallax effect doesn't show up. have added block of code responsible needed effect.

#promo {     min-height: 25em;     width: 100%;     position: relative;     z-index: 0; } <body> <section id="promo" style="background: url({{$mainimg->path}}) 50% 0px repeat fixed; background-size:cover;"> </section> </body>

the background position fixed doesnt work on mobile devices fix this, need simple trick, rather giving section background image , make fix, try make section:before , set position:fixed; , give backgroung image it.

#promo:before{ position:fixed; width:100%; height:100%; left:0; top:0; background:url('image.jpg'); }

play z-index , here go. try , let me know.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
