Well it's time to work on the logo: it's really big and we would like it to be aligned the top part of the card. There are several ways to resize an object or frame.
When an object is selected, for example, click on the logo, and you can see a red rectangle outline. This doesn't affect the object properties but only shows that it is selected. There are little red square handles at each corner and at the middle of each side. If the mouse gets over one of these handles, the cursor will change to a double arrow. If you press the left mouse button when the pointer is on one of them and then move the pointer, you'll see the size changing according to the mouse movements. Just release the button when you're done.
While resizing the frame an information box appears near the pointer and displays the new width. You will notice that the proportions of the object are not kept, and that the logo is modified. To avoid this, just press the Ctrl key while dragging...
