html - Spaces between divs and between the page -


this question has answer here:

okay sorry guys if stupid question, i've done best search possible solution or similar questions , while there questions regarding <div> spaces, solutions don't work when try implement it.

so illustrate problem. page shows this: enter image description here

when wanted show this: (edited via paint) enter image description here

here code body:

<body>     <div id="site-wrapper">         <header>             <nav id="header-panel">                 <p>welcome <?php echo $_session['name']; ?>!</p>             </nav>         </header>          <div id="core">             <div id="left-nav">                             </div>             <div id="main-core">              </div>         </div>          <footer>          </footer>     </div> </body>

now there nothing special going on in css, colors default behavior of arrangement this. i've tried changing margin, , display types of divs there's no change , still love spaces.

header {     background: #ffaa99;     font-size: 1.5em;     color: #333;     margin: 0; padding: 0; }  div{     margin: 0; padding: 0;     /* border: solid 1px black; */ } #left-nav{      background: #e0e0e0;     display: inline-block;     width: 250px; }

browsers have default style sheets includes default margins, etc. practice include css reset file removes of defaults expected behavior.

there number of sites provide code you, including:

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
