Hello 
You just have to Inspect it on a browser and play around with CSS like this way and change the top, left, right,bottom properties and try changing them on a browser , and once you get the desired result just copy that CSS from the Inspect window and paste it on to your Stylesheet

I hope this will help.

Hello Huy, 

You can the display: flex property to your container and that should fix the issue.

Or use the align center widget from OutsystemsUIWeb

Hope it helps!

Hello huy nguyen,

I can see in your OML, your checkbox has bottom-margin. You can set the bottom-margin to zero and enclose the checkbox in a separate container having width set to 'Auto'

I have shared the OML also. Please go through it.
