Having trouble styling my JQuery UI tabs in my Rails 4 app

Question

I'm using Rails 4.2.3 with the JQuery-UI plugin. I have JQuery tabs, which are set up like so

<div id="tabs">
<ul class="nav">
  <li><%= link_to 'My Objects’, root_path %></li>
  <li><%= link_to 'Lookup Results', search_times_objects_path %></li>
  <%= render 'layouts/navigation_links' %>
</ul>
</div>

and I would like to style selected tabs differently than unselected tabs, so I added this to my stylesheet …

ul.nav {
    font-family: 'russo_oneregular';
}
ul.tabs li.ui-state-active,ul.tabs li.ui-tabs-selected { 
    font-weight: bold; 
    font-color: #000000;
}
ul.tabs li.ui-tabs-active a, ul.tabs li.ui-tabs-selected a {
    font-color: #ffffff;
}

Although the stylesheet is loaded, none of the tabs is styled, even when they are selected/unselected. What do I need to adjust to get things to style properly?

To give some insight into what gets included, this is in my app/assets/javascripts/application.js file ... 要了解包含在其中的内容，这在我的app / assets / javascripts / application.js文件中...

    //= require jquery
    //= require jquery-ui
    //= require jquery_ujs
    //= require jquery.modal
    //= require turbolinks
    //= require_tree .

which renders as

        <script src="/assets/jquery.self-660adc51e0224b731d29f575a6f1ec167ba08ad06ed5deca4f1e8654c135bf4c.js?body=1" data-turbolinks-track="true"></script>

Answer 1

Problem is that from this ul.tabs li.ui-tabs-active a, ul.tabs li.ui-tabs-selected a it seems that you are looking for ul.tabs or <ul class="tabs"></ul> but you have <ul class="nav">

Try

ul.nav li.ui-state-active,ul.nav li.ui-tabs-selected { 
    font-weight: bold; 
    font-color: #000000;
}
ul.nav li.ui-tabs-active a, ul.nav li.ui-tabs-selected a {
    font-color: #ffffff;
}

Also, make sure that tabs are initialized:

$(function() {
  $( "#tabs" ).tabs();
});

Answer 2

As mentioned in other answer you should change ul.tabs to ul.nav .
And then there is no font-color CSS property, it should be color .

Below is a demo with your CSS in effect:

 $(function() { $("#tabs").tabs(); }); 

 ul.nav { font-family: 'russo_oneregular'; } ul.nav li.ui-state-active, ul.nav li.ui-tabs-selected { font-weight: bold; color: #000000; } ul.nav li.ui-tabs-active a, ul.nav li.ui-tabs-selected a { color: #ffffff; }

Answer 3

1) Do the <li> tags show the correct class in your console?
2) Are you sure your stylesheet is loaded?
3) As mentioned, use color , not font-color .
4) Looking at the jquery-ui example, it seems like li.ui-tabs-selected is selected from outside the ul , what might overwrite your css rules, especially if you load your css before jquery-ui.css

#tabs ul.tabs li.ui-state-default {
    /* test */
    color: red !important;
}
#tabs ul.tabs li.ui-state-active,
#tabs ul.tabs li.ui-tabs-selected { 
    font-weight: bold; 
    color: #000000;
}
#tabs ul.tabs li.ui-tabs-active a, 
#tabs ul.tabs li.ui-tabs-selected a {
    color: #ffffff;
}
