<p>The CSS Flags plugin / library for WordPress loads a dynamicaly created CSS with responsive flags.</p>
<p><strong>Note:</strong> CSS Flags is not a standalone plugin/library, To display the flags you will have to <a href="https://github.com/soderlind/css-flags/#example-1" rel="nofollow ugc">add code to your theme</a> using your own plugin or theme functions.php</p>
<p>You can <a href="https://soderlind.no/css-flags-plugin-for-wordpress/" rel="nofollow ugc">view the flags at my site</a></p>
<p>Sample CSS:</p>
<pre><code>.css-flag.sami {
    background-image: url('data:image/svg+xml;base64,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');

<h4>Usage</h4>
<p>The total CSS file size is 4 MB, and you don’t want to send all that data back to the users, so you <strong>must</strong> use one of the following filters in your plugin or theme.</p>
<p><strong>css_flags_countries</strong>: Load flags for one or more countries</p>
<pre><code>add_filter('css_flags_countries', function() {
    return array('no'); // Array with ISO_3166-1_alpha-2 country codes: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2#Officially_assigned_code_elements
});
</code></pre>
<p><strong>css_flags_regions</strong>: Load the flags for one or more regions. You can choose between europe, oceania, africa, asia, northamerica, southamerica and middleeast.</p>
<pre><code>add_filter('css_flags_regions', function() {
    return array('europe'); //europe, oceania, africa, asia, northamerica, southamerica, middleeast
});
</code></pre>
<p><strong>css_flags_exclude</strong>: Exclude some countries from the list. This filter must be used in combination with the <code>css_flags_countries</code> or <code>css_flags_regions</code> filters</p>
<pre><code>add_filter('css_flags_exclude', function() {
    return array('eu');
});
</code></pre>
<p><strong>css_flags_cachetime</strong>: Change the cache time, default it’s 7200 (60x60x2 = 2 hours)</p>
<pre><code>add_filter('css_flags_cachetime', function() {
    return 172800; // 2 days
});
</code></pre>
<p>If you must (but you shouldn’t), you can load all the  CSS flags using the following:</p>
<pre><code>add_filter('css_flags_countries', function() {
    return array('all'); // load all country flags (don't it's 4MB)
});
</code></pre>

More than 250 vector based flags for WordPress

<p>WP Anchor Header generates anchored headings (H1-H6), creating a heading like this:</p>
<pre><code><h2 id="the-heading">
   The Heading<a class="anchorlink dashicons-before" href="#the-heading"></a>
</h2>
</code></pre>
<p>The links are styled using the following CSS:</p>
<pre><code>/* show IDs for anchors */
h1[id]:hover a.anchorlink:before,
h2[id]:hover a.anchorlink:before,
h3[id]:hover a.anchorlink:before,
h4[id]:hover a.anchorlink:before,
h5[id]:hover a.anchorlink:before,
h6[id]:hover a.anchorlink:before {
    content: "\f103"; /*dashicons-admin-links*/
    color: #888;
    font-size: smaller;
    text-decoration: none;
    vertical-align: baseline;
}
a.anchorlink {
    text-decoration: none;
    margin-left: 0.5em;
    font-size: smaller;
}
</code></pre>

WP Anchor Header

To tell the truth I had no hope searching for a plugin that would add links to headers.
And I was so surprised when this plugin did exactly what I wanted.
Thank you, Per Soderlind, for this plugin!
P.S.: Sorry for my English, I am Russian.



Extremely useful and simple

This plugin saved me a significant amount of time adding anchor links throughout an existing website. It worked exactly as expected.

My only suggestion would be a settings panel in the admin where users can specify exactly which header elements get anchor links automatically associated with them. So for example, I can go in and select "apply anchor links to <H4> only."

The ability to have a setting to turn on/off the hover link icon would be very helpful too. I had to manually edit the CSS to hide these icons on everything but H4's in my entry content.

Awesome plugin! Great time saver! A few suggestions.
