Headline Icon to the right

There is currently no way to add a GeberateBlocks headline icon to the right of the actual heading. You can use a CSS trick to make it work, though.

Edit the Heading Block and under Advanced give it an additional CSS Class of reverse-icon.

Then write the following CSS:

.reverse-icon.gb-headline {
    order: -1;
    margin-right: 10px;
}

In case you make use of any paddings, you might want to also reverse those too. For example, if you intend to have right padding on the actual heading after the order has been reversed you would have to modify the left padding value and so on.
