无法在boostrap列上调整图像大小

Question

所以我对HTML / CSS很陌生，我从CodeAcademy上学这一课，我试图复制这个：https://s3.amazonaws.com/codecademy-content/projects/junction/index.html

问题在于，我无法让中间的图像看起来更大，它们非常小，而且我不知道如何调整它们的大小。

这是我的版本：https://jsfiddle.net/eb3roj0j/1/

Answer 1

你的css中有：

.row img
{
    position: relative;

    float: left;

    max-width: 35px;
    max-height: 35px;
}

这会限制您的图像尺寸
