javascript - Make Text visible on grey rows in a table? -


we have html code radio buttons in table:

<div class="graytitle">wie oft nutzen sie whatsapp?</div> <ul class="pageitem">     <li class="radiobutton"><span class="name">sehr oft</span>     <input name="frage10" type="radio" value="sehr oft" /></li>     <li class="radiobutton"><span class="name">mittelmäßig</span>     <input name="frage10" type="radio" value="mittel" /></li>     <li class="radiobutton"><span class="name">ehr selten</span>     <input name="frage10" type="radio" value="ehr selten" /></li> </ul>

we want grey out rows without making text invisible, have googled lot couldn't find solution. used:

for (var = 0; < document.umfrageform.frage10.length; i++) { document.umfrageform.frage10[i].style.backgroundcolor = "gray"; }

it greys out rows, including text. want text still visible after making rows grey. how can that?

disaster screenshot:

enter image description here

based on jsfiddle: stylesheet positioning span tags behind input tags, that's why don't see span remove input transparency.

what need apply background color span tags, not input tags.

[update] @alicelieutier mentioned in comments, if need support recent browsers choose apply semi-transparent background input:

for (var = 0; < document.umfrageform.frage10.length; i++) {   document.umfrageform.frage10[i].style.backgroundcolor = "rgba(0,0,0,0.7)"; }

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
