Hi miadanie11e,
I took a look at your site and this is a CSS issue. I found the code below on your site. Notice how there is a { missing after the media query. This is causing the mobile styles for below 650px to be active at all times. If you can find this block of CSS in our theme files and make the edit, you should be good.
@media only screen and (max-width:650) .home-featured-image img.alignleft {
display:block;
margin:0 auto 20px;
float:none
}
.widget-area.flexible-widgets.widget-halves .widget,
.widget-area.flexible-widgets.widget-thirds .widget, .widget-area.flexible-widgets.widget-fourths .widget {
margin-left: 0;
width: 100%;
}
.flexible-widgets {
padding: 40px 0 0
}
.site-title {
font-size: 44px
}
}
Best,
Nick
