# Add custom CSS class names for layers in your HTML exports

> You can optionally add custom CSS class names to any layers in your timeline for HTML exports, which may be useful for any kind of custom coding/development work.

If you would like to override the image scale size for any layer in your timeline, you can optionally do this for any layer by clicking any layer's **Settings** icon button in the main timeline to open the layer settings, and entering your custom CSS class name into the **Optionally include custom CSS classes to this layer in HTML exports** input field.

This will ensure that your layer will include your specified custom CSS class name to its HTML `class` attribute when they're exported to HTML from the Bannerify plugin.

> **Tip:** **Bulk applying custom CSS class name settings**. As with other layer settings, you can also apply your custom CSS class name to layers in bulk by using the [bulk apply](/bannerify/animation/animating-banners#applying-bulk-animations) feature.
