You'll need to make an extension for this, but you can use this extension to modify whatever other styles you need at the same time. The extension will be your custom styles, so let's call it that.
Start by making a new folder, call it myStyles, and add a new text document called spec.json with following:
{
"name": "myStyles",
"schemaVersion": "1.0",
"extensions": [
{
"features": [{"id":"myStyles",
"cssStyles": ["v1/ext/myStyles/styles.css"]
}],
"perspective": "common"
}
]
}
In the same folder make a new text document called styles.css with the following
.ba-tile{
height:160px !important;
border-radius: 25px;
box-shadow: 5px 10px 8px #888888;
width: 95%;
}
At the moment the folder only needs those two items, but you can obviously add as many additional items (images, css, css libraries) as you need.

Zip up the folder, and upload it as an extension to Cognos:

Reload the page and gasp in astonishment as it suddenly looks a million times better:

I've attached the extension so you can use that as a base.

How can we make the tiles smaller than the standard out of the box sizes?
