Django + Bootstrap navbar button and search field issue - html

Question

I know that there are similar questions, but I tried and searched hard and didn't find a solution for my problem. I am using Django + bootstrap to complete an exercise which include a navbar. The search button is stubbornly staying below the search field.
I would just like to align them, as in this example :
Here my code :
'''
</div>
<div class="collapse navbar-collapse justify-content-center">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<form class="form-inline my-2 my-lg-0 col-3">
<input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
<button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
</form>
</div>
<div class="collapse navbar-collapse justify-content-center" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown
</a>
<div class="dropdown-menu" aria-labelledby="navbarDropdown">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<div class="dropdown-divider"></div>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</li>
<li class="nav-item">
<a class="nav-link disabled" href="#">Disabled</a>
</li>
</ul>
</div>
</nav>
'''
Don't know if it's a naive issue, but I am really struggling and loosing time with it.
Many thanks

This is because the form-control class in the search input enforces a display: block;.
There are several solutions, depending of your needs: you can make the input inline, you can use flexbox behavior by adding the d-flex class to your form, or you can do something like that:
<form class="row g-3">
<div class="col-auto">
<input class="form-control" type="search" placeholder="Search">
</div>
<div class="col-auto">
<button type="submit" class="btn btn-outline-success mb-3">Search</button>
</div>
</form>
(btw, you can read the official docs about gutters if necessary)
Finally, please think about giving a runnable code snippet in your future questions :)
