Make articles wider / Service Desk Template change?

Rachel Campbell_w7nhd8

Our Service Desk knowledge base articles are center aligned with margins and don't stretch the width of the window. I want them to be wider in the window, maybe 3/4 wide, so half the width of the margins. I'm not sure if this is because of a Service Desk Template, can anyone help? 

I've tried looking for templates / layout / set up, and I can't find where to edit.

Here is our knowledge base 

Here is an example of an article

Hello Rachel,

Welcome to Atlassian Community!

When it comes to the customer portal and articles, currently, there is no workaround besides allowing the customer to view the articles directly in Confluence. 

They can view it without a Confluence license, but it will require to migrate their accounts to Atlassian account:

•  How can I make my users and customers see Confluence pages without a license?

There are some feature requests suggesting improvements for that:

• Use full page to display knowledge base article
• Ability to change the customer portal width.
• As a SD Customer I'd like the Portal view to expand to the width of the window

Please, click on vote and also watch the features to receive updates.

Kind regards,
Angélica
