you can use pattern multiline and singleline options:

@"^no\r?\n.*?^e\r?\n"

example:

regex rgx = new regex(@"^no\r?\n.*?^e\r?\n",       regexoptions.multiline|regexoptions.singleline); string result = rgx.replace(yourstr, "");

pattern description:

^        # anchor start of line (because multiline option           # used, otherwise ^ anchor start of string) no \r?\n    # optional carriage return , line feed .*?      # characters 0 or more times (the dot can match newlines since           # singleline option used, dot can't match newlines           # default behavior) ^        # anchor start of line e        # \r?\n    # if want preserve last crlf replace $          # ($ anchor end of line in multiline mode, in default          # mode, $ means "end of string")

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
