div 요소를 반응 적으로 만드는 방법은 무엇입니까?

Question

페이지 유형의 시장 유형이 있습니다.하지만 제품 (div 요소)이 반응적일 수는 없습니다. 창 크기를 조정하거나 모바일에서 볼 때 끔찍한 것처럼 보입니다. 여기서 내가 뭘 잘못하고 있니?

<div class="productlayout"> 
     <div class="products"> 
      <div id="col-1"> 
       <img src="originallogo.png"> 
        <hr class="lineunderproduct"> 
        <h3 class="title1">Official Mens T-Shirt</h3> 
        <h4 class="price1">$49.99</h4> 
       <button class="btn btn-5 btn-5a glyphicon glyphicon-shopping-cart"><span>Purchase</span></button> 
      </div> 

      <div id="col-2"> 
       <img src="originallogo.png"> 
        <hr class="lineunderproduct"> 
       <h3 class="title2">Mens Tank</h3> 
        <h4 class="price2">$29.99</h4> 
       <button class="btn btn-5 btn-5a glyphicon glyphicon-shopping-cart"><span>Purchase</span></button> 
      </div> 

      <div id="col-3"> 
       <img src="originallogo.png"> 
        <hr class="lineunderproduct"> 
       <h3 class="title3">Mens Sweatpants</h3> 
        <h4 class="price3">$49.99</h4> 
       <button class="btn btn-5 btn-5a glyphicon glyphicon-shopping-cart"><span>Purchase</span></button> 
      </div> 
     </div> 
    </div>

Answer 1

화면이 작아서 768 픽셀이됩니다

@media only screen and (max-width: 768px) { 

    .products { 
     display:block; 
    } 

    #col-1 {width: 100%;} 
    #col-2 {width: 100%;} 
    #col-3 {width: 100%;} 

    } 

확장 된 충격을 보려면 작은보기.

.productlayout { 
 
    display: flex; 
 
    flex-direction: row; 
 
    height: 500px; 
 
} 
 

 
.products { 
 
    display: flex; 
 
    flex-grow: 1; 
 
    background-color: #c7c4c4; 
 
    margin: 0px 40px; 
 
    justify-content: space-around; 
 
    padding: 30px 0px; 
 

 
} 
 

 
#col-1 { 
 
    background: #1d1d1d; 
 
    width: 33%; 
 
    order: 1; 
 
    box-shadow: 0px 0px 1px 1px #000; 
 
} 
 

 

 

 
#col-2 {

    width: 33%; 
 
    order: 2; 
 
    box-shadow: 0px 0px 1px 1px #000;

    width: 33%; 
 
    order: 2; 
 
    box-shadow: 0px 0px 1px 1px #000; 
 
} 
 

 

 
@media only screen and (max-width: 768px) { 
 

 
.products { 
 
\t display:block; 
 
} 
 
    
 
#col-1 {width: 100%;} 
 
#col-2 {width: 100%;} 
 
#col-3 {width: 100%;} 
 
    
 
} 
 
You need to write media queries for different view ports to make your design responsive. 
 

 

 
for smaller screen you can make add this css.

<div class="productlayout"> 
 
     <div class="products"> 
 
      <div id="col-1"> 
 
       <img src="originallogo.png"> 
 
        <hr class="lineunderproduct"> 
 
        <h3 class="title1">Official Mens T-Shirt</h3> 
 
        <h4 class="price1">$49.99</h4> 
 
       <button class="btn btn-5 btn-5a glyphicon glyphicon-shopping-cart"><span>Purchase</span></button> 
 
      </div> 
 

 
      <div id="col-2"> 
 
       <img src="originallogo.png"> 
 
        <hr class="lineunderproduct"> 
 
       <h3 class="title2">Mens Tank</h3> 
 
        <h4 class="price2">$29.99</h4> 
 
       <button class="btn btn-5 btn-5a glyphicon glyphicon-shopping-cart"><span>Purchase</span></button> 
 
      </div> 
 

 
      <div id="col-3"> 
 
       <img src="originallogo.png"> 
 
        <hr class="lineunderproduct"> 
 
       <h3 class="title3">Mens Sweatpants</h3> 
 
        <h4 class="price3">$49.99</h4> 
 
       <button class="btn btn-5 btn-5a glyphicon glyphicon-shopping-cart"><span>Purchase</span></button>
