// Allows switching between different items in the news box.
// Add more items below. HTML is supported, and is needed to add images. If it's too big, the text will disappear.

// Change only this array. Make sure to escape the single quotes like this: \'
// Or else the script won't work properly.
// Add items in the order that you wish them to appear.
