I've started to learn some html/css/javascript for fun and i'm stuck with a problem. In the html I want to display some pair of div on the same line, but i don't know why i can't do it.
The div that i want to show on the same line and at the same height are the couples of "button" and "text"
Here is my code!
html {
  background-color: #e6eeff;
  font-family: Verdana;
}
* {
  border: 1px solid black;
}
#bgCal {
  background-color: #004466;
  color: white;
  width: 500px;
  margin: 0px auto;
  border-radius: 10px;
  padding: 10px 10px 10px 10px;
}
#display {
  background-color: #d7d7c1;
  color: black;
  text-align: right;
  width: 400px;
  height: 100px;
  font-size: 30px;
  margin: 10px auto;
  line-height: 100px;
  border-radius: 5px;
}
#numberTot {
  background-color: #d7d7c1;
  vertical-align: middle;
  line-height: normal;
  margin-right: 5px;
}
.button {
  background-color: #0099e6;
  width: 150px;
  height: 60px;
  border-radius: 5px;
  margin: 10px 50px;
  display: inline-block;
  text-align: center;
  overflow: hidden;
}
.text {
  background-color: #004466;
  color: white;
  height: 60px;
  width: 180px;
  margin: 10px 50px 10px 0px;
  display: inline-block;
  text-align: center;
  font-size: 12px;
  overflow: hidden;
}<div id="bgCal">
  <div id="display">
    <span id="numberTot"> 0 </span>
  </div>
  <button class="button" onclick="numberClick(1)">+</button>
  <div class="text">
    Every click increase of 1 the total number.
  </div>
  <br>
  <button class="button" onclick="buyStudent()">
    Buy Student
    <br>Cost: <span id="studentLUCost">10</span>
    <br>Students owned: <span id="studentLevel">0</span>
  </button>
  <div class="text">
    A student can click instead of yourself, but they are slower.
    <br>
    <span id="studentProd">0</span> num/sec
  </div>
</div>
