I'm trying to create a WordPress plugin, and I would like to have jQuery UI Tabs in one of my settings pages.
I already have the scripting code set:
wp_enqueue_script('jquery'); // Enque jQuery
wp_enqueue_script('jquery-ui-core'); // Enque jQuery UI Core
wp_enqueue_script('jquery-ui-tabs'); // Enque jQuery UI Tabs
Sounds more like you have an issue with finding an available styling within WordPress for the jquery-ui theme.
To answer your question. No, WordPress has no useful styles available within the platform itself. The only available css is in \wp-includes\jquery-ui-dialog.css, and that alone isn't very useful.
I also had the same issue, and I found two options. Either store it in a CSS folder and load it from there, or load it via URL (Google APIs). For JQuery UI I decided to rely on Google's CDA and added a way to utilize the 'Theme Roller'. Storing that amount of css code seems un-nessecary to begin with, and its too bad WordPress doesn't provide any styling support like they do with the jquery-ui scripts.
wp_enqueue_style('plugin_name-admin-ui-css', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/[theme-name]/jquery-ui.css', false, PLUGIN_VERSION, false);
wp_enqueue_style('plugin_name-admin-ui-css', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/' . $pluginOptions['jquery_ui_theme'] . '/jquery-ui.css', false, PLUGIN_VERSION, false);
And an example of locally storing it
wp_enqueue_style('plugin_name-admin-ui-css', plugins_url() . '/plugin-folder-name/includes/css/jquery-ui-theme-name.css', false, PLUGIN_VERSION, false);
