javascript - Fixed divs under the bootstrap fixed nav -

-

i'd attach fixed alerts underneath navbar-fixed navigation bar in bootstrap. best attempt point make div positioned @ 50px position: fixed; , width: 100%, , insert alerts in div. problem cuts off top of other content same way navbar-fixed cuts off content when 1 fails apply padding body element.

#alerts {   position: fixed;   width: 100%;   top: 50px; } .alert {   top: 0px;   //position: fixed;   padding-left: 15px;   padding-right: 15px;   padding-top: 4px;   padding-bottom: 4px;   margin-bottom: 0px;   border-radius: 0px; } body {   padding-top: 50px; // avoid 'underlapping' navbar }

here's link not-working example: http://www.bootply.com/pnehtlhubi

my best idea @ moment use js adjust padding-top value on body alerts created/destroyed, bad maintenance/readability , i'd prefer more declarative css.

any suggestions?

looks there won't way without js.

since if alert dynamic, meaning appears when triggers via alert method

$('#alert-danger').show('slow', function(){     $('body').addclass('moremargin') });

you can remove moremargin class body when hide alert

java - UML - How would you draw a try catch in a sequence diagram? -

Image
is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
