引導網格系統

Question

我已經嘗試解決這個問題已有一段時間了……我目前正在學習Web開發，並且實現bootstrap grid-system是一種練習。 我查看了許多資源，但仍然找不到答案。

問題是，一切似乎都工作正常。 在S和XS之間的所有屏幕尺寸上。 由於某些原因，布局中斷。 當我在手機上查看時，外觀看起來相同。 我拍了一下當時的屏幕截圖。

如果有人可以幫助我，那就太好了……謝謝

Answer 1

由於您在XS設備上將有12列以上，因此我認為您僅需要為此特定視口添加一個clearfix ：

<div class="col-xs-6 col-sm-3 col-md-3"><img src="img/image4.png" class="img-responsive"></div>
<div class="col-xs-6 col-sm-3 col-md-3"><p> Test your site out on your phone. It should look like this (well, without the cats! Please replace these images with screenshots and descriptions of your own work). Test your site out on your phone. It should look like this (well, without the cats! </p></div>

<div class="clearfix visible-xs-block"></div>

<div class="col-xs-6 col-sm-3  col-md-3"><img src="img/image4.png" class="img-responsive"></div>
<div class="col-xs-6 col-sm-3 col-md-3"><p> Test your site out on your phone. It should look like this (well, without the cats! Please replace these images with screenshots and descriptions of your own work). Test your site out on your phone. It should look like this (well, without the cats! </p></div>

Answer 2

+-----------+-----------+
|sm-6       |sm-6       |
|+----+----+|+----+----+|
||xs-6|xs-6|||xs-6|xs-6||
|+----+----+|+----+----+|
+-----------+-----------+

這就是您想要的方式，每行不能超過12col

什么時候需要做xs6 + xs6 | xs6 + xs6 xs6 + xs6 | xs6 + xs6您將必須使用嵌套行，並且父行將在需要時拆分。
