css - Setting body { font-size: 100% } results in font-size: 12px; and not font-size: 16px; Why? -


i understood default font-size 16px on browsers. why height of inline-block(12px) same font-size (i've tried in chrome , ff) ? please me understand. thank you.

<!doctype html> <html> <head>     <style>         body {             font: 100% helvetica, arial, sans-serif;             line-height: 1.625;         }         #temptest {             display: inline-block;             width: 10px;             height: 12px;             background-color: orange;         }     </style> </head> <body> <p class="heading"><span id="temptest"></span>remember, when young, shone sun. shine on crazy diamond</p> </body> </html>

if inspect inline box using browser’s developer tools (hit f12 open them), can see height indeed 12px, set in code. happens because there nothing in require more height; in general, exact calculation of heights of inline blocks browser-dependent.

the font size of text still browser default, typically 16px. font size not mean height of particular letter. fundamental property of font; typographers design characters - ascenders, descenders, , diacritic marks - fit limits set font size (or extend on them little), , letters have smaller height.

javascript - Mootools wait with Fx.Morph start -

i trying var effect = new fx.morph(testmorph, { wait/delay 2 seconds before starting. ( fiddle here ) but when try .wait(2000) or .delay(2000) , or .wait(2000, effect) uncaught typeerror: object [object object] has no method 'delay' any ideas how working? code i'm using: var testmorph = document.id('testmorph'); var effect = new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start({ 'top': 20, 'opacity': 1 }).start({ 'border-color': '#a80025', 'color': '#a80025' }); effect.delay(2000); you can use combination of chain() , delay() achieve desired effect. new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start().chain(function(){ this.start.delay(2000,effect,{ //first }); }).chain(function(){ this.start({ //second }); }); the
