How to align font awesome and text using flex box - html

Question

I'm doing some homework and I'm trying to reproduce this
right here
this is my code
<div class="filterbar">
<p>Filtres</p>
<button class="buttonfilter Eco"> <i class="fas fa-money-bill-wave fa-2x"></i> Economique</button>
<button class="buttonfilter Fam"> <i class="fas fa-child fa-2x"></i>Famillial</button>
<button class="buttonfilter Rom"> <i class="fas fa-heart fa-2x"></i>Romantique</button>
<button class="buttonfilter Pet"> <i class="fas fa-dog fa-2x"></i>Animaux autorisé</button>
</div>
CSS right here
.filterbar{
display: flex;
max-width: 1100px;
margin: 0 auto;
overflow: auto;
}
.filterbar p {
font-weight: bold;
font-size: 18px;
margin-top: 10px;
margin-right: 20px;
}
.buttonfilter{
display: flex;
align-items: stretch;
height: 50px;
background: none;
border: 4px solid var(--background);
border-radius: 30px;
padding: 0;
}
.fa-money-bill-wave,.fa-child,.fa-heart,.fa-dog {
color: var(--primary-color);
background: rgba(0,101,252,0.2);
border-radius: 100px;
}
and the thing is that I can't align the font awesome icon and the text, and the background of the font awesome is so strange I really don't understand

I have litte modified your code:
.filterbar{
display: flex;
max-width: 1100px;
width: 1100px;
margin: 0 auto;
overflow: auto;
justify-content: space-between;
}
.filterbar p {
font-weight: bold;
font-size: 18px;
margin-top: 10px;
margin-right: 20px;
}
.buttonfilter{
display: flex;
align-items: stretch;
height: 50px;
background: none;
border: 4px solid var(--background);
border-radius: 30px;
padding: 0;
align-items: center;
border: 1px solid #333;
padding-right: 10px;
}
.fa-money-bill-wave,.fa-child,.fa-heart,.fa-dog {
color: var(--primary-color);
background: rgba(0,101,252,0.2);
border-radius: 100px;
padding: 10px;
margin-right: 10px;
width: 35px;
}

Answer 2

To show the fontawsome Icons you need to put in the source like this:
<script src="https://kit.fontawesome.com/a076d05399.js" crossorigin="anonymous
This worked for me:
<script src="https://kit.fontawesome.com/a076d05399.js" crossorigin="anonymous"></script>
<i class="fas fa-money-bill-wave fa-2x"></i><button>Economique</button>
<i class="fas fa-child fa-2x"></i>
<button>Famillial</button>
<i class="fas fa-heart fa-2x"></i>
<button>Romantique</button>
<i class="fas fa-dog fa-2x"></i>
<button>Animaux autorise</button>
I think at this point you can adjust it yourself :)
