Трехстолпная сетка для масонства

Question

Я хочу показать сетку из 3-х колонных изображений на рабочем столе и одну колонку на устройстве. Следующий план работает на мобильных устройствах, но не работает на рабочем столе (большой разрыв между двумя изображениями). Я пытался установить ширину в процентах, но не повезло

.block{
    float: left;
    margin: 2px 2px 2px 2px;
    width: calc(33.33% - 17px);
}

.block img {
    width: 100%;
    height: auto;
}

@media only screen and (max-width: 500px) {
  .block {
      float: left;
      margin-bottom: 25px;
      width: calc(100% - 17px);
  }
}

заранее спасибо

Answer 1

Вы, вероятно, захотите использовать только медиа-запросы и удалить float,

Конструкция ниже очень гибкая и позволяет

• Одна колонка на мобильных экранах
• Две колонки на планшете
• Три колонки на маленьких настольных экранах / ноутбуках
• Четыре колонны на больших рабочих столах
• Пять колонок на 4к экранах.

Остальные комментарии находятся внутри фрагмента.

body {
  background: #131418;
}


/* Step 1: start with resetting some defaults */

* {
  margin: 0 auto;
  padding: 0;
  max-width: 100%;
}


/* Step 2: center things inside the grid and clear some space around it by setting a device based max-width and margin*/

.grid {
  text-align: center;
  max-width: 95vw;
  margin: 2.5vw auto;
}


/* Step 3: how big should the gap be between grid items? remember that the total gap between two items would be double what you set here since both would have that amount set as their individual padding. Also add box-sizing:border-box to make sure the padding doesn't affect the total widh of the item */

.grid-item {
  padding: 5px;
  box-sizing: border-box;
}


/* Step 4: Add media queries (subjective) to make the whole grid resposive. */

@media (min-width: 500px) {
  .grid-item {
    width: 50%;
  }
}

@media (min-width: 1000px) {
  .grid-item {
    width: 33.333%;
  }
}

@media (min-width: 1700px) {
  .grid-item {
    width: 25%;
  }
}

@media (min-width: 2100px) {
  .grid-item {
    width: 20%;
  }
}

<!-- Part 1: Add the scripts -->

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<!-- Step 2: Then load imagesloaded. imagesloaded makes sure the images are not displayed until they are fully loaded -->

<!-- Part 3: the script call -->

<!-- Now that everything is loaded we create a script to trigger masonary on $grid. Note that this simply says: "if the images are fully loaded, trigger masnory on $grid. -->
<script>
  var $grid = $(".grid").imagesLoaded(function() {
    $grid.masonry({
      itemSelector: ".grid-item"
    });
  });
