Kifurushi kinachobadilika na Vipimo kwenye CSS

Sasa tufanye kifurushi chenye vipimo. Huu ni mfano wa kile tunachotakiwa kufikia:

Kwanza tufanye mitindo kwa mzazi wa vizuia:

css.parent {
  display: flex;
  flex-wrap: wrap;
  width: 95%;
  margin: 50px auto;
}

Sasa tuweke mitindo kwa vizuia vyenyewe, bila kuwapa upana, lakini tukiwapa ukingo wa chini kwa asilimia:

css.child {
  box-sizing: border-box;
  height: 100px;
  padding: 20px;
  margin-bottom: 1.5%;
  border: 1px solid green;
}

Sasa tuandike msimbo ambao utaweka vizuia vinne kwenye mstari mmoja, ukiweka viingilio vinavyofanana:

css@media (min-width: 1000px) {
  .child {
    width: calc(100% / 4 - 1.5% * 3 / 4);
  }
  .child:not(:nth-child(4n)) {
    margin-right: 1.5%;
  }
}

Sasa tuweke vizuia vitatu kwenye mstari mmoja:

css@media (min-width: 700px) and (max-width: 1000px) {
  .child {
    width: calc(100% / 3 - 1.5% * 2 / 3);
  }
  .child:not(:nth-child(3n)) {
    margin-right: 1.5%;
  }
}

Sasa tuweke vizuia viwili kwenye mstari mmoja:

css@media (min-width: 400px) and (max-width: 700px) {
  .child {
    width: calc(100% / 2 - 1.5% * 1 / 2);
  }
  .child:not(:nth-child(2n)) {
    margin-right: 1.5%;
  }
}

Kizuia kimoja kwenye mstari mmoja:

css@media (max-width: 400px) {
  .child {
    width: 100%;
  }
}

Sasa tukusanye msimbo wote pamoja:

css.parent {
  display: flex;
  flex-wrap: wrap;
  width: 95%;
  margin: 50px auto;
}
.child {
  box-sizing: border-box;
  height: 100px;
  padding: 20px;
  margin-bottom: 1.5%;
  border: 1px solid green;
}

@media (max-width: 400px) {
  .child {
    width: 100%;
  }
}
@media (min-width: 400px) and (max-width: 700px) {
  .child {
    width: calc(100% / 2 - 1.5% * 1 / 2);
  }
  .child:not(:nth-child(2n)) {
    margin-right: 1.5%;
  }
}
@media (min-width: 700px) and (max-width: 1000px) {
  .child {
    width: calc(100% / 3 - 1.5% * 2 / 3);
  }
  .child:not(:nth-child(3n)) {
    margin-right: 1.5%;
  }
}
@media (min-width: 1000px) {
  .child {
    width: calc(100% / 4 - 1.5% * 3 / 4);
  }
  .child:not(:nth-child(4n)) {
    margin-right: 1.5%;
  }
}
