html - Font size - percentage mess - and workarounds -


i figured out span not inherit div's font-size, consider on 50% 100%. so, following example won't same 100% span, because 100% is: 16(100%)-8(50%)+4(50% of 50%)= 12px(150% <span>). needed 200% same.

my question is: can done that, if want use %. there workarounds(something css reset - it's different, know)? if not, best alternative making more simple development, yet effective responsiveness styling?

css:

body {   font-size: 16px; } div {   font-size: 50%; } div > p > span {   font-size: 150%; }

html:

<div>   p p p   <p>     <span>       span     </span>   </p> </div>

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
