Button alignment when text box shrinks (CSS) - html

Question

Alright, what I am trying to do is, I want the button beside my text box to be aligned beside the text box whenever my page resize, which would cause my text box to shrink or expand accordingly ( as you can see below in the following snippet) Can someone help me out here? Thanks in advance for the help!
function myFunction() {
var x = document.getElementById("myTopnav");
if (x.className === "topnav") {
x.className += " responsive";
} else {
x.className = "topnav";
}
}
.topnav {
background-color: transparent;

Remove absolute positioning from both .test and .searchFeature, then wrap them in a flexbox. I also recommend adding a min-width to the input.
HTML:
<div class="search-wrapper">
<input type="text" class="searchFeature" ng-model="selected" ng-keyup="$event.keyCode == 13 && searchFunction()" uib-typeahead="value for value in themename | filter:$viewValue | limitTo:7" placeholder="Start your search here...">
<button class="test">Test</button>
</div>
CSS:
.search-wrapper {
display: flex;
flex-direction: row;
}
.test {}
.searchFeature {
border: 1px solid #999;
padding: 3px 18px 3px 4px; /* Use the same right padding (18) in jQ! */
border-radius: 3px;
/* transition: background 0.4s; */
width:40%;
}
