# Post Settings
This group of settings controls the look and layout of your posts.
### Enable image lightbox:
This will control the opening of images and gallery images in a lightbox popup. Lightbox is a javascript library that will open the image in a popup, as shown below. You can navigate through the images using lightbox.
If you disable the lightbox, then the images will appear as it is without the ability to click on them and see the larger version. As you can see in the below image, all images appear smaller in size and it becomes difficult to see them when used in a gallery card.
### Show tags in post hero:
If enabled, then this will show the tags in the post header, as shown below.
### Enable code syntax highlight:
This will enable to highlight code syntax. This is specifically useful if you are planning to add some code snippets in your website. If you are not going to use any code, then I highly suggest to disable this. Enabling this will load a javascript library which increases the load time. So, please disabe it if not used.
If enabled, then the code snippets will be displayed as below.
If disabled, the code will not be highlighted and will appear in monospace as below.
