div外部的框架

Question

我有此代码：

.section_mop_5_2019 {
  background-image: url("../images/ob100_2019.png");
  background-position: right;
  background-repeat: no-repeat;
  background-size: cover;
  font-family: 'rajdhani_regular_webfont';
  padding-bottom: 180px;
  padding-top: 60px;
}

.etapy_2019 {
  text-align: center;
  text-transform: uppercase;
  font-size: 36px;
  color: #262626;
  font-weight: bold;
}

.etapy_2019_all_1 {
  background-color: #A91B1C;
  color: #F2F3FF;
  padding: 30px;
}

.etapy_2019_all_2 {
  background-color: #803066;
  color: #F2F3FF;
  padding: 30px;
}

.etapy_2019_all_3 {
  background-color: #38408B;
  color: #F2F3FF;
  padding: 30px;
}

.etapy_2019_all_4 {
  background-color: #603B7D;
  color: #F2F3FF;
  padding: 30px;
}

.etapy_2019_all_5 {
  background-color: #225F6F;
  color: #F2F3FF;
  padding: 30px;
}

.etapy_2019_tytul {
  text-transform: uppercase;
  text-align: center;
  font-size: 18px;
  font-weight: bold;
  padding-bottom: 20px;
}

.etapy_2019_tresc {
  font-size: 14px;
  text-align: justify;
}

.etapy_2019_all_pad {
  padding: 30px;
}

.etapy_2019_rejestracja {
  font-size: 28px;
  padding-left: 60px;
  padding-top: 30px;
}

.gabinety_obrazek_2019_1 {
  clear: both;
  padding-top: 25px;
  padding-left: 60px;
}

.gabinety_tel_2019 {
  color: #333333;
  font-size: 32px;
  font-weight: bold;
  font-family: 'rajdhani_regular_webfont';
  line-height: 1.1;
