Divide in circles with responsive layout

Question

I’m trying to make a page that contains div in circles and which fit one below the other when the layout decrease, for example, to cell phone sizes. With the common size I would like them to be 4 side-by-side and when decreasing they are below each other. I read something about media queries and I’m trying to implement, but in case anyone knows and could help me with something.

I can’t leave a little space between the div.

Follow the code I’m currently using:

.center-content {
  border: solid 1px #000;
  width: 100%;
}

.center-content div {
  border-radius: 50%;
  display: table-cell;
  vertical-align: middle;
  text-align: center;
  width: 100px;
  height: 100px;
  background-color: #229922;
}

<div class="center-content">
  <div>Texto</div>
  <div>Texto</div>
  <div>Texto</div>
  <div>Texto</div>
  <br/>
  <div>Texto</div>
  <div>Texto</div>
  <div>Texto</div>
  <div>Texto</div>
</div>

Answer 1

I was able to find two alternatives:

1. Using inline-block
2. Using inline-flex

Using inline-block

To have more coverage you can use the display inline-block thus:

.master {
	border: solid 1px #000;
	max-width: 500px;
    font-size: 0;
}

.master div {
    border-radius: 50%;
    display: inline-block;
    text-align: center;
    margin: 10px;
    width: 100px;
    line-height: 100px;
    background-color: #229922;
    font-size: 40px;
}

body{
    color: white;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button onclick="$('.master').width($('.master').width()-25)">Clique para reduzir largura em 25px</button>
<button onclick="$('.master').width($('.master').width()+25)">Clique para reduzir largura em 25px</button>
<div class="master">
    <div>1</div>
    <div>2</div>
    <div>3</div>
    <div>4</div>
    <div>5</div>
    <div>6</div>
    <div>7</div>
    <div>8</div>
</div>

Using inline-flex

If you have no restrictions on using some more modern CSS like inline-flex, can do so:

.master {
	border: solid 1px #000;
	max-width: 500px;
    font-size: 0;
}

.master div {
    border-radius: 50%;
    display: inline-flex;
    align-items: center;
    justify-content: center;
    margin: 10px;
    width: 100px;
    height: 100px;
    background-color: #229922;
    font-size: 40px;
}


body{
    color: white;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button onclick="$('.master').width($('.master').width()-25)">Clique para reduzir largura em 25px</button>
<button onclick="$('.master').width($('.master').width()+25)">Clique para reduzir largura em 25px</button>
<div class="master">
    <div>1</div>
    <div>2</div>
    <div>3</div>
    <div>4</div>
    <div>5</div>
    <div>6</div>
    <div>7</div>
    <div>8</div>
</div>
