Don’t use floats for this, use flexbox instead. You can also use display: grid; but for your simple layout flexbox should do the job just fine.

div.post {
  min-height: 40px;
  display: flex;
  flex-wrap: wrap;
}

div.a {
  flex: 0 0 30%;
  background-color: green;
  min-height: 40px;
  border: 1px solid;
}

div.b {
  flex: 0 0 35%;
  background-color: blue;
  min-height: 40px;
  border: 1px solid;
}

div.c {
  flex: 0 0 35%;
  background-color: yellow;
  min-height: 40px;
  border: 1px solid;
}

This seems like a perfect example to use CSS Grid, you can read about it here:

You could have something like this:

.container {
  display: grid;
  grid-template-columns: 30% 35% 35%;
}

.a {
 grid-column-start: 1;
 grid-column-end: 2;
 background-color: green;
  min-height: 40px;
  border: 1px solid;
}

.b {
 grid-column-start: 2;
 grid-column-end: 3;
 background-color: blue;
  min-height: 40px;
  border: 1px solid;
}

.c {
 grid-column-start: 3;
 grid-column-end: 4;
   background-color: yellow;
  min-height: 40px;
  border: 1px solid;
}

You should use flex or grid for the layouts instead of float left and right.
See the below working demo.

div.post {
  min-height: 40px;
}

p.a {
  width: 30%;
  background-color: green;
  min-height: 40px;
  border: 1px solid;
}

p.b {
  width: 35%;
  background-color: blue;
  min-height: 40px;
  border: 1px solid;
}

p.c {
  width: 35%;
  background-color: yellow;
  min-height: 40px;
  border: 1px solid;
}
