you loading xml content, not it's css. change html css, have change source of file dynamically:

$(document).ready(function() {    $('.btn').click(function() {      $('#style').attr('href', $(this).data('url'))    });  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <link rel="stylesheet" type="text/css" href="https://bootswatch.com/cerulean/bootstrap.min.css" id="style">  <div class="wrapper">    <div class="btn btn-success" data-url="https://bootswatch.com/cerulean/bootstrap.min.css">style 1</div>    <div class="btn btn-primary" data-url="https://bootswatch.com/slate/bootstrap.min.css">style 2</div>  </div>

css - SVG using textPath a symbol not rendering in Firefox -

using textpath within symbol doesn't render in firefox. renders fine in latest chrome , ie, when try reference symbol, svg text doesn't render in firefox (37.0.1) - first box appears empty. code below (no external dependencies), there should 2 boxes word test flowing vertically in centre of each. edit: thought issue somehow involved flexbox layout, until paul pointed out issue exists without flexbox layout. the html is: <div> <svg id="not_working" viewbox="0 0 250 1200" preserveaspectratio="xmidymid meet"> <symbol id="test_symbol1" preserveaspectratio="xmidymid meet" viewbox="0 0 250 1200"> <path id="test_symbol_path" d="m 100 1200 l 100 0" /> <text font-size="100" fill="red"> <textpath text-anchor="middle" startoffset="50%" xlink:href="#test_symbol_path&q
