Where should you show the banner with the Cassiopeia template?

Normally, you can show the banner anywhere on your website. However, if you are utilizing the Cassiopeia template, it’s a good idea for you to display it on the suggested position below.

  • Using module position Topbar to show the banner:

If you use this module position, your banner will appear at the very top. Besides that, your banner will be expanded to the full width of the screen. You can see the following image as an example of that.

When you use the module position, your banner will be located below the topbar position but above the logo or the alternative text. However, your banner won’t be extended to the full width of the screen. Let’s check out our example of the module position below-top here.

Style the banner module

Because the screen widths of electronic devices are different, sometimes the banner cannot cover the full width of the container. To fix this, you should specify the minimum size of the banner to be 100%. To do this, let’s add the imported “my-banner” class to the banner first.

Now, you need to switch your editor from text mode to code mode. For TinyMCE, you just need to press Toggle Editor. For JCE, do it with the Code tab. In our example below, we are using the WYSIWYG editor, so we will open Tools -> Source Code.

A popup Source Code will appear and it contains the code of the image banner you added. Thus, you simply insert class=”my-banner” like the descriptive image below.

Don’t forget to save it. After that, let’s save all your settings for the module by pressing on the Save or Save & Close button at the top of the screen.

.my-banner {
