如何使用CSS使特定部分完全对齐？

标签： html css mobile

我正尝试使用css，html和javascript从头开始重新创建此图形。 这是原始的： Recreate Image

这是我的版本 enter image description here

我遇到的问题是在移动尺寸和1024px尺寸下完美地调整关键规格。但是我没有运气。我正在使用flexbox，当时我正在考虑将方向用作一种方法，但我不知道容器div或什么位置。 我不想使用Bootstrap之类的框架。我需要从头开始。你能取悦我吗？非常感谢

有几种方法可以实现这一目标。

静态

最简单但最脆弱的方法是将顶部包裹在delimiter中，确定最高盒子的高度，并将其设置为CSS中的<div>。但是，如果文本太长或在不同的屏幕尺寸下框会调整宽度，则会遇到可维护性问题。

HTML 

min-height

CSS 

<li class="item item1">
    <div class="item-intro">
        <img src="images/chromebookpro.jpg">
        <h2>Google Pixelbook</h2>
        <p class="pricing">Starting at $999</p>
        <p>The first high performance Chromebook with Google Assistent built in. Features a four-in-one design offering laptop, tablet, tent, and entertainment modes, an all day battery with fast charging, a sleek aluminum body, and an optional pen. </p>
    </div>
    <div class="item-text-specs">
        <p class="item-specs"> Key Specs</p>
        <div class="item-list">
            <p class="article">12.3" Quad HD LCD</p>
            <p class="article">Intel processor&reg;</p>
        </div>
        <div class="item-list">
            <p class="article">128/256/512 GB</p>
            <p class="article">8/16 GB memory</p>
        </div>
    </div>
</li>

动态-纯CSS

另一个选择是在顶部和底部项目说明中打两个框。然后使用.item-intro { min-height: 300px; } ，可以使高度自动匹配。但这对于移动响应而言变得复杂，并且将需要使用flexbox。您也可以使用order来达到类似的目的。

HTML 

grid

CSS 

<ul class="item-list">

    <!-- Item 1 Start-->
    <li class="item item1">
        <img src="images/chromebookpro.jpg">

    </div>
    <!-- Item 2 End-->

    <!-- Item 3 Start-->

        <div class="item-list">
            <p class="article">0.53" thin</p>
            <p class="article">4/8 GB memory</p>
        </div>
    </div>
    <!-- Item 3 End-->

</ul>

动态-JS

最终选择是编写一个JavaScript代码段，该代码段循环遍历顶部的框，找到最高的框，并将该高度应用于所有框。如 Static 示例中所述，您将必须修改HTML以分隔.item, .item-text-specs { flex: 0 1 100%; } /* Only needed for desktop */ @media (max-width: 768px) { .item-text-specs.item1 { order: 4; } .item-text-specs.item2 { order: 5; } .item-text-specs.item3 { order: 6; } } 中的顶部描述。我不会写Javascript，因为它很耗时，但是应该相对简单。如果框的宽度也发生变化，则最困难的功能将是在窗口大小发生变化时触发高度调整。因此，根据您对Javascript的熟悉程度，使用jQuery可能会更容易。
