Flexbox Or Column CSS For Positioning Elements Like This

Is there any solution to avoid the float and to use flexbox and make this type of layout like in my representation? I don't have any example but this picture with what I need. I'll

Solution 1:

If you combine Flexbox with absolute position, you can accomplish that.

What I did was to make use of the order property to position the red element in the upper right corner. With this one can then control its position using media queries.

To force a wrap on the end of the 2nd row, I used a pseudo element with the same size as the right_corner element, and use the order property to position it.

To center the red element I use an absolute positioned wrapper and Flexbox, that will take twice its height, and by that cover 2 rows.

Stack snippet

.container {
  display: flex;
  flex-wrap: wrap;
  counter-reset: num;
}

.container .right_corner > div {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: calc(200% + 10px);
  display: flex;
  justify-content: center;
  align-items: center;
}

.container .right_corner > div > div {
  width: 300px;
  min-width: 300px;
  height: 250px;
  background: red;
}

.container::before,
.container > div {
  height: 150px;
  margin: 5px;
}

.container > div:not(:first-child) {
  background: lightgray;
}

.container .right_corner {
  position: relative;
  order: 1;
}

.container::before {
  content: '';
  order: 3;
}

.container > div:nth-child(n+2)::before {
  counter-increment: num;
  content: counter(num);
}

@media (max-width: 800px){
  .container > div:nth-child(n+4) {
    order: 2;
  }
  .container > div:nth-child(n+6) {
    order: 4;
  }
  .container > div:not(:first-child) {
    width: calc((100% / 4) - 10px);
  }
  .container .right_corner {
    width: calc((100% / 2) - 10px);
  }
  .container::before {
    width: calc((100% / 2) - 10px);
  } 
}

@media (min-width: 801px) and (max-width: 1000px){
  .container > div:nth-child(n+5) {
    order: 2;
  }
  .container > div:nth-child(n+8) {
    order: 4;
  }
  .container > div:not(:first-child) {
    width: calc((100% / 5) - 10px);
  }
  .container .right_corner {
    width: calc((100% / 2.5) - 10px);
  }
  .container::before {
    width: calc((100% / 2.5) - 10px);
  } 
}

@media (min-width: 1000px) {
  .container > div:nth-child(n+6) {
    order: 2;
  }
  .container > div:nth-child(n+10) {
    order: 4;
  }
  .container > div:not(:first-child) {
    width: calc((100% / 6) - 10px);
  }
  .container .right_corner {
    width: calc((100% / 3) - 10px);
  }
  .container::before {
    width: calc((100% / 3) - 10px);
  }
}

<div class='container'>

  <div class='right_corner'>
    <div>
      <div></div>
    </div>
  </div>

  <div></div>
  <div></div>
  <div></div>
  <div></div>

  <div></div>

Solution 2:

My attempt on jsfiddle.net. It is without absolute positioning and pseudo elements.

And the same code here in the below snippet:

body {
  background-color: black;  
}

.grid {
  display: flex;
  flex-flow: row wrap;
}

.grid > div {
  display: flex;
  justify-content: center;
  align-items: center;
}

.item {
  width: calc(33.33% - 10px);
  margin: 5px;
  height: 60px;
  background-color: gainsboro;  
}

.red-box {
  box-sizing: border-box;
  width: calc(33.33% - 60px);
  margin: 30px 30px;
  height: 80px;
  margin-bottom: -70px; 
  order: 2!important;
  background-color: red;
  border: 2px solid gainsboro;      
}

.red-box > div {
  background-color: red;
  height: 60%;
  width: 60%;
  border: 2px solid gainsboro; 
}    

@media (max-width: 499px) {
  .grid > div:nth-child(-n+3) {
    order: 1;
  }
  .grid > div:nth-child(n+4) {
    order: 3;
  }      
  .grid>div:nth-child(5) {
    margin-right: calc(33.33% + 5px);
  }
}

@media (min-width: 500px) and (max-width: 999px) {
  .grid > div:nth-child(-n+4) {
    order: 1;
  }
  .grid > div:nth-child(n+5) {
    order: 3;
  } 
  
  .item {
    width: calc(25% - 10px);
   }
   .red-box {
    width: calc(25% - 60px);
   }
   .grid>div:nth-child(7) {
     margin-right: calc(25% + 5px);
   }
}

@media (min-width: 1000px) {
  .grid > div:nth-child(-n+5) {
    order: 1;
  }
  .grid > div:nth-child(n+6) {
    order: 3;
  } 
  
  .item {
    width: calc(20% - 10px);
   }
   .red-box {
    width: calc(20% - 60px);
   }
   .grid>div:nth-child(9) {
     margin-right: calc(20% + 5px);
   }
}
