html5 - Change Nav Label Color Using CSS -


trying work out active state nav issue single-page website comprised of series of content slides. slides html5 sections, each discreet id.

i found js solution insert active state main navigation here. nav menu in fixed-position sidebar.

however, have pictogram nav elements @ top , bottom of each slide can used scroll next / previous slide. these not trigger click event js looks for.

any ideas on how insert active state when clicking on pictograms, well?

here's current js:

<script>      $(document).ready(function () {     $('#mainnav ul li a').on("click", function () {         $(this).parent().siblings().find("a").removeclass('active');         $(this).addclass('active');     });     });  </script>

here's main nav, again in fixed position sidebar:

<nav role="navigation">      <div id="mainnav">          <ul class="mainnavcontainer clearfix">              <li class="mainnavrows"><a href="#foo1" title="">foo 1</a></li>             <li class="mainnavrows"><a href="#foo2" title="" >foo 2</a></li>             <li class="mainnavrows"><a href="#foo3" title="" >foo 3</a></li>             etc...          </ul><!--end mainnavcontainer-->      </div><!--end mainnav-->  </nav>

here's basic structure of slides. includes pictogram nav elements target same ids main nav does:

<section id="foo1">      <!--pictogram nav element referencing prev slide (if exists)-->      <div class="abovescroll">           <a href="#background"><span class="icon">&#59239;</span></a>      </div>      ...slide content...      <!--pictogram nav element referencing next slide (if exists)-->      <div class="bottomscroll">           <a href="#believe"><span class="icon">&#59236;</span></a>      </div>  </section> etc...

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
