regex - Sed remove from match until match -


i want remove parts of file starting match (including first match) , until second match (excluding second match). file looks this, another question:

3. line 3 4. line 4 ## screenshots ## 1. line 1 2. line 2 3. line 3 4. line 4 ## changelog ## 3. line 3 4. line 4

from answers of the other question have taken sed command outputs ## screenshots ## until 4. line 4, before ## changelog ##. however, remove section file.

to clarify, know next section start ##, ## foobar ## know :)

i have tried replace print commands delete commands so

sed -e '/## screensh/,/##/{/scree/{d;n};/##/{q};d}' file

but did not work because stops output after second match, ## changelog ## in case (because of quit command). have tried use regex character class match # character sed -n '/## screenshots ##[^#]*/p' prints ## screenshots ##.

something this:

sed '/## screenshot/,/##/{/screenshot/d;/##/!d}'

that's - delete between 2 matches, including first not including last. if know section ends '## changelog ##' becomes just

sed '/## screenshot/,/##/{/## changelog/!d}'

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; } ...
