Quick Search Text Box and Search Button in single line

when the browser is in full size the Quick Search text box and search button is showing in single line.and when the browser is small or open in a mobile browser the search box and button is showing in 2 line
How can I make both the search box and search button in a single line when the browser is small also

I have try with
.ew-ext-search-form {
display: inline-block;
}
and also
.ew-ext-search-form {
display: inline-block;
overflow-x: auto;
}It does not bring the Quick Search Box and Search Button in a single line when the browser is small or open at mobile

You may change the CSS class of the div containing the search button, e.g. change “col-sm-auto” to “col-12”. See Grid system.
