make input and span next to each other

Question

Trying to align input and span next to each other. Span is positioned below input ,how to align span on right side of input. I wanted to create a search bar with this input and span tag hence want to align next to each other

I have placed both of them inside one division yet it is not positioned correctly

is there any css property missing out or any css is given incorrectly in my code

Answer 1

Add display: flex; to your .search-form

Take a look at flexbox, it is a more modern method for solving a lot of layout challenges. https://css-tricks.com/snippets/css/a-guide-to-flexbox/

#custom-search-input {
  margin:0;
  margin-top: 10px;
  padding: 0;

}

.form-control{
  border-radius: 0;
}
#custom-search-input .search-query {
  padding-right: 3px;
  padding-right: 4px \9;
  padding-left: 3px;
  padding-left: 4px \9;
  border: 1px solid   #494949 ;
  /* border-right-style: none; */
  margin-bottom: 0;
}

#custom-search-input button {
  background-color:rgb(0,0,0,0.3) ;
  height: calc(1.5em + .75rem + 2px);
  padding: 2px 10px;
  position: relative;
  vertical-align: middle;
}
.ion-android-search{
  font-size: 150%;
}
.btn-danger{
  border:none;
  border-radius: 0;
}
.search-query:focus + button {
  z-index: 3;   
}
 .search-form {
  width: 100%;
  display: flex;
  flex-wrap: wrap;
}

.search-input{
  flex-grow: 1;
}

.search-form input:focus + .results { display: block }

.search-form .results {
  display: none;
