Carregando
</button>

The idea is to put animation of the right or left slime of the word "carrying", something like this:

|=================|
|  **  Carregando |
|=================|

or

|=================|
|  Carregando  ** |
|=================|

Asterisk(**) is animation. Some solution ?

Answer 1

As the height of the animation is fixed as well as the margins, you can use line-height with these values, which gives 62px in total and add on button:

button.btn-outline-primary{
  line-height: 62px;
}

To align left, you can use the Bootstrap class float-left in div animation parent. You also need to change the edges of the animation so it doesn’t stick to the text (I used 10px in the right margin, but you can use whatever you want):

.sk-cube-grid {
  width: 30px;
  height: 30px;
  margin: 16px 10px 0 0;
}               ↑
          margem direita

If you want the animation on the right, use the class float-right and adjust the margin to the left:

.sk-cube-grid {
  width: 30px;
  height: 30px;
  margin: 16px 0 0 10px;
    }               ↑
              margem esquerda

Example:

button.btn-outline-primary{
  line-height: 62px;
}

.sk-cube-grid {
  width: 30px;
  height: 30px;
  margin: 16px 10px 0 0;
}

.sk-cube-grid .sk-cube {
  width: 33%;
  height: 33%;
  background-color: #333;
  float: left;
  -webkit-animation: sk-cubeGridScaleDelay 1.3s infinite ease-in-out;
  animation: sk-cubeGridScaleDelay 1.3s infinite ease-in-out;
}

.sk-cube-grid .sk-cube1 {
  -webkit-animation-delay: 0.2s;
  animation-delay: 0.2s;
}

.sk-cube-grid .sk-cube2 {
  -webkit-animation-delay: 0.3s;
  animation-delay: 0.3s;
}

.sk-cube-grid .sk-cube3 {
  -webkit-animation-delay: 0.4s;
  animation-delay: 0.4s;
}

.sk-cube-grid .sk-cube4 {
  -webkit-animation-delay: 0.1s;
  animation-delay: 0.1s;
}

.sk-cube-grid .sk-cube5 {
  -webkit-animation-delay: 0.2s;
  animation-delay: 0.2s;
}

.sk-cube-grid .sk-cube6 {
  -webkit-animation-delay: 0.3s;
  animation-delay: 0.3s;
}

.sk-cube-grid .sk-cube7 {
  -webkit-animation-delay: 0s;
  animation-delay: 0s;
}

.sk-cube-grid .sk-cube8 {
  -webkit-animation-delay: 0.1s;
  animation-delay: 0.1s;
}

.sk-cube-grid .sk-cube9 {
  -webkit-animation-delay: 0.2s;
  animation-delay: 0.2s;
}

@-webkit-keyframes sk-cubeGridScaleDelay {
  0%,
  70%,
  100% {
    -webkit-transform: scale3D(1, 1, 1);
    transform: scale3D(1, 1, 1);
  }
  35% {
    -webkit-transform: scale3D(0, 0, 1);
    transform: scale3D(0, 0, 1);
  }
}

@keyframes sk-cubeGridScaleDelay {
  0%,

    transform: scale3D(1, 1, 1);
