You can do that quite simple using flexbox:
#container {
/* margin-top: 500px; */
width: 1000px;
margin: 0 auto;
}
.related-article {
background-color: #D6A400;
display: inline-block;
border-radius: 30px;
margin-bottom: 0px;
}
.related-article > img {
width: 200px;
height: 150px;
border-radius: 15px;
margin-top: 15px;
}
.related-article > h3 {
font-size: 15px;
width: 180px;
text-align: justify;
margin-left: auto;
margin-right: auto;
color: #f1f1f1;
font-family: Abel, serif;
margin-bottom: none;
}
a {
text-decoration: none;
}
}
#container {
width: 1000px;
}
.related-article {
background-color: #D6A400;
display: inline-block;
width: 230px;
height: 300px;
border-radius: 30px;
margin-bottom: 0px;
}
.related-article > img {
width: 200px;
height: 150px;
border-radius: 15px;
margin-top: 15px;
}
.related-article > h3 {
font-size: 15px;
width: 180px;
text-align: justify;
margin-left: auto;
margin-right: auto;
color: #f1f1f1;
font-family: Abel, serif;
margin-bottom: none;
}
a {
text-decoration: none;
}
.box {
margin-right: 10px;
width: 230px;
height: 300px;
}
.flex-container {
display: flex;
align-items: center;
justify-content: center;
}
