Html margin problem - & ldquo; Shaking & rdquo; Website


Im working on a Website and everything is ok, except my webside is "shaking". (I'm using chrome) The margin of my main Container is changing on some sides and i have no idea why. They have the same html code, it must have something to do with the content in the main div-container

My Website: is a bit more to the left and after getting a task (just click some buttons) also.

Has someone a idea?

You could add

html{ overflow-y: scroll;}

to your css.

Places a permanent (but sometimes empty) scroll bar on the window
