Why these two elements are not aligned in one line? - html

Question

I'm trying to align these input forms to one line. If I take them separately - it works. Just trying to make it responsive. I want them to be in one line for desktop and move one below another for mobile.
I'm using these styles to create to make forms responsive and they work separately. But when I add other styles of my page there is a conflict and it's not working anymore

Answer 1

try it with flexbox:
<div class="container">
<div class="form1 flex-item">
form
</div>
<div class="form2 flex-item">
form2
</div>
</div>
css:
.container{
display: flex;
-webkit-flex-flow: row wrap;
flex-flow: row wrap;
}
.flex-item{
width: 50%;
#media (max-width: 600px){
width: 100%;
}
}
