i trying implement sticky footer flexible box layout model implemented in recent versions of chrome , firefox. given markup inside body element: <header> header </header> <div> content </div> <footer> footer </footer> my idea use following css: html, body { height: 100%; } body { margin: 0; display: -webkit-flex; display: flex; -webkit-flex-direction: column; flex-direction: column; } div { -webkit-flex: 1; flex: 1; } footer { background-color: yellow; } this works fine long content less 100% of viewport height. when content becomes larger, however, chrome 28 begins paint footer on top of content. buggy behaviour (and if: how can workaround it) or css wrong? you can test chrome's behaviour here: http://jsfiddle.net/symjp/ . firefox display thing intended. chrome/chromium 25/26. if regression in recent chrome versions, bug reported? added apparent error persists in chrome ...

why happening? have no code in test: [testclass] public class apiclienttest { [testmethod] public void apitestsampleusecase() { testcleanup(); } public void testcleanup() { //deleteusers(); } } yet when run this, takes ~1 minute complete. passes, takes forever. set breakpoint after deleteusers , gets hit immediately; delay after test has completed. check bin directory - incomprehensible reason, mstest copies referenced assemblies new directory every time run tests. (these safe delete, though.) maybe else causes slow down after many runs... according this answer , this documentation , can disable behaviour. i'd recommend switching nunit if possible, preferrably in combination fluentassertions (due not insignificant number of weird design decisions in mstest, such behaviour, lack of easy-to-use parameterized tests, , fact test run if [testinitialize] throws exception).
