html - Why style a lists -

-

what point in styling ul? have following html structure

<div id='container'> <div id='ui' class='quad'>     <div class='quadnav'>         <span class='quadtitle'>urgent , important</span>         <i class="fa fa-plus fa-2x addbutton"></i>     </div>     <ul class='tasklist'>         <li>test</li>         <li>test2</li>     </ul> </div>

and following css styling list

.tasklist{  } .tasklist li{   list-style-type:none;   position:relative;   top:2em;   left:1.2em;  }

with .tasklist section empty li elements style want them to. if remove .tasklist section, li's no longer style. gives? supposed go styling of ul element vs li element, don't understand.

edit may not have worded question, have following css

<style>     /* -------- general styling ---------*/     *{         margin:0;         padding:0;     }      html, body {         font-size:20px;     }      #container{       width:100%;       height:100%;       position:absolute;       top:0;       left:0;     }      /*--------quadrant style ------- */     .quad{         position: relative;         width: 49.85%;         height: 49.8%;         font-size: .8em;         border: solid 1px black;     }      #ui{         float: left;         background-color: green;     }      #nui{         float: right;         background-color: red;     }      #uni{         float: left;         background-color: blue;     }      #nuni{         float:right;         background-color:yellow;     }         /*------- quadrant navigation styling ------- */ .quadnav{   position:relative;   width:100%;   top:1em; } .quadtitle{   position: relative;   left:1em; } .addbutton{   position:relative;   float:right;   right: 1em; } /*---------- task list styling ----------*/' .tasklist{  } .tasklist li{   list-style-type:none;   position:relative;   top:2em;   left:1.2em;  }

when remove empty .tasklist{} declaration .tasklist li styles stop working. trying figure out why.

this happen if have error in preceding css, e.g.

.broken {     /* note no closing brace */  .tasklist{  } .tasklist li{   list-style-type:none;   position:relative;   top:2em;   left:1.2em; }

now, .tasklist { line inside .broken {...} block, , closing brace .tasklist closes that, following .tasklist li { block works ok. if remove .tasklist block, wind .tasklist li styling inside erroneous block, , styling stops working.

edit: in updated code, can see problem stray apostrophe on line

/*---------- task list styling ----------*/'

remove trailing ' , fix it

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 $row): ?> <div id="<?=$...
