CSS Cardio

I took the CSS Grid course on the 19th day of March. I downloaded first all of the videos and study repeatedly offline. I tweeted updates regarding my progress on Twitter (see here). I didn't study everyday because I have some things to do and finally today, I finished the course.

On the 11th video, there's the Spanning and Placing Cardio.

      /* Make the grid have 10 explicit rows, 50px high each */

    }

    /* With Item 1, start at col 3 and go until 5 */

    /* With Item 2, start at col 5 and go until the end */

    /* Make Item 5 double span 2 cols and rows */

    /* Make Item 8 two rows high */

    /* Make Item 15 span the entire grid width */

    /* Make item 18 span 4 widths, but end 9 */

    /* Make item 20 start at row 4 and go for 3 */
  </style>

My Answer

I paused the video and answered it. Here's my answer:

/* Maria Kristina Salada - 04-05-2020 */
    .container {
      display: grid;
      grid-gap: 20px;
      /* Make the grid 10 columns wide, every other taking up twice the free space */
      grid-template-columns: repeat(10, 2fr);
      /* Make the grid have 10 explicit rows, 50px high each */
      grid-template-rows: repeat(10, 50px);
    }

    /* With Item 1, start at col 3 and go until 5 */
    .item1 { grid-column: 3 / 5; }
    /* With Item 2, start at col 5 and go until the end */
    .item2 { grid-column: 5 / -1; }
    /* Make Item 5 double span 2 cols and rows */
    .item5 { grid-column: span 2; grid-row: span 2; }
    /* Make Item 8 two rows high */
    .item8 { grid-row: span 2; }
    /* Make Item 15 span the entire grid width */
    .item15 { grid-column: 1 / -1; }
    /* Make item 18 span 4 widths, but end 9 */
    .item18 { grid-column: span 4 / 9; }
    /* Make item 20 start at row 4 and go for 3 */
    .item20 { grid-row: 4 / span 3; }

Correct Answer

Here's the correct answer:

.container {
      display: grid;
      grid-gap: 20px;
      /* Make the grid 10 columns wide, every other taking up twice the free space */
      grid-template-columns: repeat(5, 1fr 2fr);

      /* Make the grid have 10 explicit rows, 50px high each */
      grid-template-rows: repeat(10, 50px);
    }

    /* With Item 1, start at col 3 and go until 5 */

    .item1 {
      grid-column: 3 / 5;
    }

    /* With Item 2, start at col 5 and go until the end */

    .item2 {
      grid-column: 5 / -1;
    }

    /* Make Item 5 double span 2 cols and rows */

    .item5 {
      grid-column: span 2;
      grid-row: span 2;
    }

    /* Make Item 8 two rows high */

    .item8 {
      grid-row: span 2;
    }

    /* Make Item 15 span the entire grid width */

    .item15 {
      grid-column: 1 / -1;
    }

    /* Make item 18 span 4 widths, but end 9 */

    .item18 {
      grid-column: span 4 / 9;
    }

    /* Make item 20 start at row 4 and go for 3 */

    .item20 {
      grid-row: 4 / span 3;
    }

I only got one wrong answer. The codes are really different but result is almost the same.

Thanks to Wes Bos, the teacher for the course and to Mozilla for that free course about CSS Grid. You can also take the course. I recommended it for learning CSS Grid because it's fun and informative. Just go to cssgrid.io and sign up.
