TaskAppend link to the bottom of Content Query Web Parts that show articles from News subsite so that users can click the link to view more news articles of the specific category.
The picture below is in Finnish, but link at the bottom called “Lisää…” is the one added using jQuery. Also the CQWP style is quite heavily modified, but I’m sure you get the point.
SolutionNot being a fan of custom CQWP implementations for this purpose nor modifying the out-of-the-box XSL Style Sheets using SharePoint Designer, I decided to solve this using jQuery.

Note that you need to use the starts with selector (^=), as the actual HTML node title attribute contains also other text after the actual title you define in web part properties. For the style moreNews, you can define what you see best, I just added some padding around the link. For the link I redirect the user to a site pages library view that has metadata filtering enabled and visible on the left: this is done using the TreeField and TreeValue parameters.
For SharePoint Online, use code such as this:
