How to use media queries to fit the website to mobile view

Question

I am using media queries for the responsive website. But whenever the browser window size decreases the media queries will be applied according to the size. But the media query is not applied to the website whenever the browser size is set to mobile view. How to wrote those queries? this is my css and html .Whenever the is less than 760px the content should be margin right. How to do that?

@media all screen and (min-width:410) and (max-width:760px) {
  .image2 {
    display: flex;
    flex-wrap: wrap;
    margin-right: 1000%
  }
}

Answer 1

You forgot px in min-width and do not use all

See fiddle:https://jsfiddle.net/6180Lub2/

    @media screen and (max-width:760px ) and (min-width:410px)  {
             .image2 {
            display: flex;
            flex-wrap: wrap;
            margin-right: 1000%
        }

          }
