Hi filipa.martins,

We have not tested with the Content Switcher plugins or any recommended plugins. We are sorry for this.

Go to Appearance -> Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save all changes button:

#main form input{
  padding: 10px;
  border: 1px solid rgba(0, 0, 0, 0.05);
  width: 100%;
  margin: 0 0 30px;
  background-color: #f9f9f9;
}

select.wpcf7-form-control.wpcf7-select.wpcf7-validates-as-required {
  border: 1px solid rgba(0, 0, 0, 0.05);
  width: 100%;
  margin: 0 0 30px;
  background-color: #f9f9f9;
  height: 50px;
}

Thank you!
