CSS列（照片网格）显示从左到右而不是从上到下

Question

我使用列来创建照片网格，它们可以将所有提供的照片放在一起，而不会在它们之间留下任何空白。

这里是我使用的CSS：

.autofit-photo-grid { 
    /* Prevent vertical gaps */ 
    line-height: 0; 
    -webkit-column-count: 3; 
    -webkit-column-gap: 0; 
    -moz-column-count: 3; 
    -moz-column-gap: 0; 
    column-count: 3; 
    column-gap: 0; 
} 

.autofit-photo-grid img { 
    /* Just in case there are inline attributes */ 
    width: 100% !important; 
    height: auto !important; 
    border: 1px solid #777; 
    opacity: 0.85; 
} 

下面是该问题的样本小提琴：https://jsfiddle.net/es7hLuq4/

如果你将鼠标悬停在每个图像，你会看到，他们说：“照片1 ”，‘照片2’等，但顺序是这样的

1 4 7 
2 5 8 
3 6 9 

但我想它是这样的

1 2 3 
4 5 6 
7 8 9 

这是纯粹的CSS可能吗？如果没有，是否有任何干净的jQuery解决方案可以帮助？我想过关于每个图像元素的循环，并试图检查它在哪个列，但这似乎很混乱（将不得不重新调整大小），我也不知道如何检查一个元素当前在哪一列。

任何想法如何实现相同的自适应网格效果，但列出连续的项目从左到右而不是从上到下？

我以矩阵索引中的每个图像解决的问题。第一个完成的版本有点粗糙，并且有时会在相邻图像的纵横比差别很大时重新排序。

我将处理更新后的版本，该版本对图片尺寸进行了说明，并在完成时更新答案和小提琴。

我用这个JS/jQuery的供试品重配置功能：

// define currentColumnCount outside the function scope so it can be compared when window is resized 
var currentColumnCount; 

var attributeToIndex; // switch to src for actual, title for debug/human-readable 

function rearrangePhotos(performRearrange) { 
    // if not performing rearragement, index titles instead of src for debug/human 
    attributeToIndex = (!performRearrange) ? 'title' : 'src'; 

    // get current number of columns being displayed 
    currentColumnCount = $('.autofit-photo-grid').css('column-count'); 

    // create arrays to store values in 
    var originalPhotoMatrix, reversePhotoMatrix, columnPerimeters; 
    originalPhotoMatrix = new Array(); 
    reversePhotoMatrix = new Array(); 
    columnPerimeters = new Array(); 

    // loop through all the images to compare their left & top perimeters to determine their cell position 
    $('.autofit-photo-grid img').each(function() { 
    // if the left perimeter is not found in the array, its a new column 
    if (columnPerimeters.indexOf($(this).offset().left) == -1) 
     columnPerimeters[columnPerimeters.length] = $(this).offset().left; // create new columnPerimeter record 

    }); // end loop 

    // sort the columns to be in consecutive order 
    columnPerimeters = columnPerimeters.sort(function(a, b) { 
    return a - b 
    }); 

    // now that we have the perimeters of each column, let's figure out which cell each photo belongs to 
    var colCounter = 1; 
    var rowCounter = 1; 
    // loop through all the raw image objects again 
    $('.autofit-photo-grid img').each(function() { 
    // get the current position of the image again to determine which column it's in 
    var currentOffset = $(this).offset().left; 
    // get the column based on the position of the current image 
    var currentCol = columnPerimeters.indexOf(currentOffset) + 1; 

    // if we encounter a new column, reset and increment our col/row counters accordingly 
    if (currentCol != colCounter) { 
     colCounter++; 
     rowCounter = 1; 
    } 

     // assign the matrix index to a data attr on the img 
    $(this).attr('data-matrix-key', rowCounter + ',' + colCounter); 
    // assign original and reverse matrix values 
    originalPhotoMatrix[rowCounter + ',' + colCounter] = $(this).attr(attributeToIndex); 
    reversePhotoMatrix[colCounter + ',' + rowCounter] = $(this).attr(attributeToIndex); 

    // increment the row counter before restarting the loop 
    rowCounter++; 
    }); // end loop 



    // sort the original matrix by key so that it's in the proper order before generating key list for 
    // final version of reversePhotoMatrix 
    originalPhotoMatrix = ksort(originalPhotoMatrix); 

    // assign matrix id by looping through existing matrix keys/indexes 
    var availableKeys = new Array(); // create array to store keys/indexes in 
    for (var key in originalPhotoMatrix) { // loop through the keys and contents of the original matrix 
    availableKeys[availableKeys.length] = key; // add this key to the list of available keys 
    } // end loop 


    // generate the new photo matrix based on the next available key from the old matrix 
    var c = 0; // intialize counter 
    reversePhotoMatrix = new Array(); // clear array to prevent any unused/leftover/nonexistent values from lingering 
    // loop through the images....AGAIN 
    $('.autofit-photo-grid img').each(function() { 
    // determine the next available matrix key/index based on the current counter value 
    var nextAvailableKey = availableKeys[c]; 
    // reassign new key/index and value to reverse photo matrix 
    reversePhotoMatrix[nextAvailableKey] = $(this).attr(attributeToIndex); 

    c++; // increment the counter before restarting the loop 
    }); // end loop 



    // finally, loop through all the original matrix items and grab the corresponding item from the reverse matrix 
    console.log("\n\nRearrange ready\n\n"); // just a console comment 
    // loop through all keys and values in the original matrix 
    for (var key in originalPhotoMatrix) { 
    if (!performRearrange) // if performRearrange=false, only display console output 
     console.log('Swap ' + originalPhotoMatrix[key] + ' with ' + reversePhotoMatrix[key]); 
    if (performRearrange) // if performRearrange=true, perform the actual rearrangement 
     $('.autofit-photo-grid img[data-matrix-key="' + key + '"]').attr(attributeToIndex, reversePhotoMatrix[key]); 
    } // end loop 


} // end rearrangePhotos function 



// This is just to attach the click event to the text/link at the top 
$('.rearrange-link').click(function() { 
    // on the first click, call rearrangePhotos(performRearrange=false) 
    rearrangePhotos(false); 
    // Now change the link text to instruct the next click 
    $(this).text('Now rearrange them'); 
    // Now attempt to rearrange the actual photo sources with rearrangePhotos(performRearrange=true) 
    $(this).click(function() { 
    rearrangePhotos(true); 
    }); 
}); 

// Run the rearrangePhotos() function everytime the window size is adjusted 
$(window).resize(function() { 
    if (currentColumnCount != $('.autofit-photo-grid').css('column-count')) 
    rearrangePhotos(false); 
});

这会按照您想要的方式排列项目并保持图像的纵横比。但图像具有固定的高度，因此与原来的图像调整行为稍有不同。 https://jsfiddle.net/s1bppsjo/2/
