html - Is `position: fixed` on `<body>` problematic? -


on spa mobile devices , desktop browsers need set position: fixed on <body> avoid ios' overflow/rubberband scrolling.

position: fixed , modifications on <body> hacky , risky cause problems.

this why wanted clarify:

are there known problems / caveats / things watch out (i.e. stacking context, z-indexing context, static/relative/absolute/fixed positioning on children) / ... when adding position: fixed <body>

the "position: fixed" relates "element" positioned relative browser window. webpage browser zooming affected it. ie6 , below break it.

perhaps better as:

html, body { height: 100%; overflow: auto; }  body .element { position:fixed; bottom: 0; }

then html:

<body> <div class="element">     (everything else inside here) </div> </body>

This guest post is by Phil (not his real name) of somehighschoolblog . It used to be impossible to run a business anonymously. Sure, some authors could pull it off, but if you worked at an office, what were you supposed to do? Go to work with a bag over your head? But today anyone can accomplish this, because anyone can author a blog (and you thought I was going to tell you to work with a mask on, or something).
