Code Examples

While WordPress and its plugins mainly operate via a GUI, you can still add custom HTML, CSS, and JavaScript to enhance your gallery or slideshow.

For instance, to add a custom CSS class to your gallery, you can use the following snippet:

<div class="my-custom-gallery">
    <!-- Insert your gallery shortcode here -->
</div>

To style your gallery using custom CSS, you can add the following to your theme's style.css file:

.my-custom-gallery .envira-gallery-item {
    border: 2px solid #fff;
}

These examples add a custom class to your gallery and use CSS to add a white border to each image in the gallery.
