html - Equal-width form labels with arbitrary horizontal rules -


i have horizontal label: <input> style form. labels need equal widths, dynamic - based on longest label in form. normally, i'd solve series of display: table/row/cell elements, need horizontal rule separating some of these rows.

display: table not play non-row/cell elements inside it.

the core form structure:

<form>     <div class="group">       <span>test</span>       <div class="field">         <input type="text">       </div>     </div>     <hr>     <div class="group">       <span>test long</span>       <div class="field">         <input type="text">       </div>     </div>     <div class="group">       <span>test</span>       <div class="field">         <input type="text">       </div>     </div>   </form>

the css:

* { box-sizing: border-box; } html, body { width: 100%; }  form {   display: table;   border-collapse: collapse;   border-spacing: 0;   width: 100%;   border: 1px solid red; }  .group {   display: table-row; }  span {   display: table-cell;   background: #ddd;   padding: 0 10px 0 0;   white-space: nowrap;   width: 1px; }  input, hr {   width: 100%; }

the label widths work i'd expect, yet hr cannot fill 100% width. can right width making position: absolute, lose spacing between rows. can make display: table-row no longer have control on spacing.

jsbin

this funny one.

i don't know how strict design here ok solution.

hr{   display:table-cell;   padding:10px 0;   border:none;   box-sizing:content-box;   background:black;   height:1px;   background-clip:content-box; }

using table-cell on hr can expand full width, little trick on padding , background-clip can have simple horizontal line. if want take further can add image background , use repeat-x expand in full width.

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

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
