How to make bar smaller across bottom

Take a look at the bar across the bottom of the picture and someone tell me how to make in narrower. There are two of course and if there were one would pretty much take care of the problem. Thanks in advance. Are these tool bars or task bars and what is the difference.

Hello there.

Place the cursor on the edge of the taskbar, click it and drag it until you find it comfortable, then, right click the taskbar and click "Lock the taskbar", that's it

Got it

Thanks, done. I should have used lock the task bar a long time ago. Now I have the 24 inch display I paid for and not a 19 inch!

You're Welcome

Remember if you want to adjust it again, just unlock it, adjust it and lock it in place
