moim zdaniem rozwiązanie z flexem nie jest za dobre, wystarczyło zrobić tak
* {
box-sizing: border-box;
margin: 0;
padding: 0;
}
html,
body {
font-family: 'Exo 2', sans-serif;
background-color: #F6F6F6
}
.box {
margin-top: 10px;
background: white;
padding: 20px;
width: 70%;
margin: auto;
margin-top: 80px;
}
.tags {
margin-top: 20px;
margin-bottom: 20px;
text-align:center;
}
.tags a {
border: 2px solid #ecf0f1;
padding: 7px;
text-transform: uppercase;
font-size: 12px;
color: #95a5a6;
text-decoration: none;
}
.tags a:hover {
border: 2px solid #e67e22;
color: #e67e22;
}
.button {
border: 2px solid #e67e22;
color: #e67e22;
padding: 7px;
text-decoration: none;
display: inline-block;
font-size: 12px;
font-weight: 800;
background-color: Transparent;
}
.button:hover {
-webkit-transition-duration: .4s;
transition-duration: .4s;
cursor: pointer;
background-color: #e67e22;
color: #ecf0f1;
}
