FontAwesome inherits parent font-size causing bad rednering -

-

each fontawesome icon set inherit font-size of parent. however, font best rendered @ specific sizes , if parent has different font-size: 14px; effect icon quality. question is, why use css this

.fa {font-size: none;} .fa-lg {font-size: 1.33333333em;} .fa-2x {font-size: 2em;} .fa-3x {font-size: 3em;} .fa-4x {font-size: 4em;} .fa-5x {font-size: 5em;}

without knowing what's parent font-size , therefore risk having badly rendered icons , not have this

.fa {font-size: 14px;} .fa-lg {font-size: 19px;} .fa-2x {font-size: 28px;} .fa-3x {font-size: 42px;} .fa-4x {font-size: 56px;} .fa-5x {font-size: 70px;}

where make sure each icon has best possible quality.

so, know why font-awesome using 'em' units on 'px'. right?

reason:

lets have heading text (<h1>) of size 30px. , paragraph (<p>) text of 14px. both has icons.

so, if font-awesome icons in fixed size 14px, render body text. small in heading tags, icon in 14px , heading text in 30px.

if use relative size, can use parent's font size, icon , text wont in different sizes.

also, if have fixed size, , if doesn't match website's font size, need manually reset font size every time. people use '13px' base font size , have '15px'.

we don't know users font size particular element, , that's why using em , rem units.

if not clear, sorry :(

thanks!

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
