Mobile landing page width problem

hi everyone, new to unbounce
im using unbounce to make a landing page which have desktop and mobile version
but i got some problem about the width of the mobile page
the width didnt fixed and it can move left and right like browsing desktop page
and i hope the width can be fixed and just show whatever is in the 320 width.

thank you so much if you can answer my question!

Hi @Tszyan_Yip welcome to the community! :smiley:

A common mistake is that one of your elements from the desktop version is somewhere far in the width of the mobile version and you just need to drag it in place or hide it. I suggest you make sure you can account for all your page elements on mobile to see if anything is outside of view.
