grid布局

基本属性

容器属性

在父元素中写入display: grid; 使其转为grid容器

创建显式网格(创建行与列)

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. <div class="item">item7</div>
  9. <div class="item">item8</div>
  10. <div class="item">item9</div>
  11. </div>
  1. .cnt{
  2. /* 转换为grid网格容器 */
  3. display: grid;
  4. /* 相同并且相邻的值,可以用repeat()简化 (个数, 比例 单位用fr) */
  5. /* grid-template-columns /rows: 1fr 2fr 1fr; 使用不同比例操作*/
  6. grid-template-columns: repeat(3, 1fr);
  7. grid-template-rows: repeat(3, 1fr);
  8. }

排列规则

grid-auto-flow: row/column; row默认 column垂直排列

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. <div class="item">item7</div>
  9. <div class="item">item8</div>
  10. <div class="item">item9</div>
  11. </div>
  1. .cnt{
  2. /* 转换为grid网格容器 */
  3. display: grid;
  4. grid-template-columns: repeat(3, 1fr);
  5. grid-template-rows: repeat(3, 1fr);
  6. /*默认 row*/
  7. /*grid-auto-flow: row;*/
  8. /*column垂直排列*/
  9. grid-auto-flow: column;
  10. }


隐式网格

grid-auto-rows: 1fr 超出固定高度后自动分配位置

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. <div class="item">item7</div>
  9. <div class="item">item8</div>
  10. <div class="item">item9</div>
  11. <div class="item">item10</div>
  12. <div class="item">item11</div>
  13. <div class="item">item12</div>
  14. </div>
  1. .cnt{
  2. /* 转换为grid网格容器 */
  3. display: grid;
  4. grid-template-columns: repeat(3, 1fr);
  5. grid-template-rows: repeat(3, 1fr);
  6. /* 超出显示网格数量的子元素,创建在隐式网格中(自动分配位置) */
  7. grid-auto-rows: 1fr;
  8. }

对齐方式

子元素在容器中对齐方式 两个值
place-content: 垂直方向 水平方向; start center end

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. </div>
  1. .cnt{
  2. width: 500px;
  3. height: 500px;
  4. background-color: antiquewhite;
  5. /* 转换为grid网格容器 */
  6. display: grid;
  7. /*子元素宽度总和需要小于父元素才会有效果*/
  8. grid-template-columns: repeat(3, 100px);
  9. grid-template-rows: repeat(3, 100px);
  10. /*垂直居中 水平靠右*/
  11. place-content: center end;
  12. /* 如果两个值相同,可以简写 */
  13. place-content: center;
  14. /* 剩余空间还可以在所有项目之间进行分配 两个值相同,可以简写*/
  15. place-content: space-between space-around;
  16. }





控制子元素在网格中 垂直方向 水平方向

place-items: 垂直方向 水平方向 可选值start center end

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. </div>
  1. .cnt{
  2. width: 500px;
  3. height: 500px;
  4. background-color: antiquewhite;
  5. /* 转换为grid网格容器 */
  6. display: grid;
  7. /*子元素宽度总和需要小于父元素才会有效果*/
  8. grid-template-columns: repeat(3, 100px);
  9. grid-template-rows: repeat(3, 100px);
  10. /*place-items: 垂直方向 水平方向*/
  11. place-items: center center;
  12. }
  13. .cnt > .item{
  14. width: 100px;
  15. height: 100px;
  16. background-color: blue;
  17. }

相对于单元格调整对齐方式

place-self: 垂直方向 水平方向 可选值start center end

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. </div>
  1. .cnt{
  2. width: 500px;
  3. height: 500px;
  4. background-color: antiquewhite;
  5. /* 转换为grid网格容器 */
  6. display: grid;
  7. /*子元素宽度总和需要小于父元素才会有效果*/
  8. grid-template-columns: repeat(3, 100px);
  9. grid-template-rows: repeat(3, 100px);
  10. }
  11. .cnt > .item{
  12. width: 100px;
  13. height: 100px;
  14. background-color: blue;
  15. }
  16. .cnt .item:first-child{
  17. /* 相对于单元格调整对齐方式 */
  18. place-self: center end;
  19. }

单元格跨越多个行列

grid-column/row: 开始 结束

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. </div>
  1. .cnt{
  2. width: 500px;
  3. height: 500px;
  4. background-color: antiquewhite;
  5. /* 转换为grid网格容器 */
  6. display: grid;
  7. /*子元素宽度总和需要小于父元素才会有效果*/
  8. grid-template-columns: repeat(3, 100px);
  9. grid-template-rows: repeat(3, 100px);
  10. }
  11. .cnt > .item{
  12. width: 100px;
  13. height: 100px;
  14. background-color: blue;
  15. }
  16. .cnt .item:first-child{
  17. /* 跨越单元格 */
  18. grid-row: 2;
  19. grid-column: 1;
  20. background-color: firebrick;
  21. }

  1. .cnt .item:first-child{
  2. width: auto;
  3. /* 占据多个单元格 */
  4. /* grid-area: 行开始 / 列开始 / 行结束 / 列结束; */
  5. /* tips: 如果是span 1 可以简化,如果span 1不在最后位置不能简化 */
  6. grid-area: 1 / 2 / span 2 / span 2;
  7. background-color: firebrick;
  8. }

行列间隙

gap: 垂直方向 水平方向

  1. <div class="cnt">
  2. <div class="item">item1</div>
  3. <div class="item">item2</div>
  4. <div class="item">item3</div>
  5. <div class="item">item4</div>
  6. <div class="item">item5</div>
  7. <div class="item">item6</div>
  8. </div>
  1. .cnt{
  2. width: 500px;
  3. height: 500px;
  4. background-color: antiquewhite;
  5. /* 转换为grid网格容器 */
  6. display: grid;
  7. /*子元素宽度总和需要小于父元素才会有效果*/
  8. grid-template-columns: repeat(3, 100px);
  9. grid-template-rows: repeat(3, 100px);
  10. /* 行列间隙 垂直方向 水平方向 数值相同可以简写*/
  11. gap: 5px 5px;
  12. }

总结

  1. /* 转换为grid网格容器 */
  2. display: grid;
  3. /* 创建显式网格 */
  4. /* 相同并且相邻的值,可以用repeat()简化 (个数, 比例 单位用fr) */
  5. /* grid-template-columns /rows: 1fr 2fr 1fr; 使用不同比例操作*/
  6. grid-template-columns: repeat(3, 1fr);
  7. grid-template-rows: repeat(3, 1fr);
  8. /* 排列规则 */
  9. /* row行优先 默认 column 垂直排列*/
  10. grid-auto-flow: row;
  11. grid-auto-flow: column;
  12. /* 隐式网格 */
  13. /* 超出显示网格数量的子元素,创建在隐式网格中(自动分配位置) */
  14. grid-auto-rows: 1fr;
  15. /* 子元素在容器中对齐方式 两个值*/
  16. /* place-content: 垂直方向 水平方向; */
  17. /* 可选值start center end */
  18. place-content: center end;
  19. /* 剩余空间还可以在所有项目之间进行分配 */
  20. place-content: space-around space-between;
  21. place-content: space-between space-around;
  22. place-content: space-between;
  23. place-content: space-around;
  24. /*控制子元素在网格中 垂直方向 水平方向*/
  25. /* place-items: 垂直方向 水平方向; 两个值*/
  26. /* 可选值start center end */
  27. /* 与上方相同 */
  28. place-items: start center;
  29. place-items: center center;
  30. place-items: center end;
  31. place-items: center center;
  32. /* 行列间隙 垂直方向 水平方向 数值相同可以简写*/
  33. gap: 5px 5px;
  34. item
  35. /* 相对于单元格调整对齐方式 */
  36. /* place-self: 垂直方向 水平方向; */
  37. /* 可选值start/center/end; */
  38. place-self: center end;
  39. /* 跨越单元格 */
  40. grid-row: 2;
  41. grid-column: 1;
  42. /* 占据多个单元格 */
  43. grid-row: 2 / span 1;
  44. grid-column: 2 / span 2;
  45. /* grid-area: 行开始 / 列开始 / 行结束 / 列结束; */
  46. /* tips: 如果是span 1 可以简化,如果span 1不在最后位置不能简化 */
  47. grid-area: 1 / 2 / span 2 / span 2;

结合案例:可以配合着 flex布局一起使用会更轻松
