How to fix adaptiv?

Here is the website

For iPhone 5/SE, that is, when the screen width is less than 340px, then there is a space on the right side.
Can't understand where it comes from. But if you hide the block "Feedback" then everything is fine.

Solution
Here it's the problem, something prevents him to be pressed down less 340 px. It is possible that some elements inside have the property display: flex, then the model to try to set flex-wrap: wrap to the elements overflow is transferred to a new line.

Without code it is difficult to say more precisely (sitting with a mobile and can't open your website with devtools)

It turns out my block "Feedback" in the background Martinica png for its transparency did this space
img {max-width: 100%; height: auto; }
And backgrounds are logical to do the background, K. O. - ryley.Balistreri commented on April 7th 20 at 15:45
