Embedding Custom HTML Snippets into Headers & Footers - All Catalogs


  • Coursedog’s catalog product gives institutions the option to customize their public catalog fully, from the color of web elements to including branded assets like logos in the navigation and footer.

  • One of Coursedog’s most asked about features is the HTML snippet function. In the Website Settings tab within Settings, users have the ability to inject HTML snippets before the page (as a header) or after the page (as a footer).

HTML Snippet Best Practices

HTML Snippets Should be Fully Standalone

As a best practice, HTML snippets should be delivered fully standalone. That means the HTML renders correctly without depending on any external CSS. This website is a great resource to ensure that this is the case. If the code is pasted into the “HTML” rectangle, and the resulting image looks correct in the “Result” rectangle on the bottom right of the page, the snippet should be good to use.

Ensure Class Names are Unique (If You Want CSS Rules inside the HTML)

  • If CSS rules inside the HTML are also desired (which is possible), users should ensure that all the class names are very unique. As a rule of thumb, prefix all class names with school_code+injected. This should prevent any possible collisions with the website itself.

  • Example – .dbu-injected-navigation-button

Avoid Javascript

  • Javascript code embedded within the header is more difficult for our catalog builder to accommodate. While HTML and CSS is oftentimes straightforward, Javascript adds another layer of complexity that could potentially impact the functionality of the catalog as a whole.

  • It is recommended NOT to use Javascript.
