img src

在这个数字化的时代，图片已成为我们生活中不可或缺的一部分。无论是社交媒体上的分享，还是网页上的装饰，img src标签都扮演着重要的角色。它不仅让我们的信息更加丰富多样，也让我们的生活更加便捷。下面，就让我们一起探索img src的奥秘吧。

img src，全称image source，是HTML中用于插入图片的标签。它可以让网页更加生动有趣，让信息传递更加直观。下面，我们将从以下几个方面详细介绍img src的使用方法。

1. img src的基本属性

img src标签具有以下基本属性：

（1）src：指定图片的路径，是img标签中最重要的属性。它可以是一个绝对路径，也可以是一个相对路径。

（2）alt：当图片无法加载时，alt属性中的文本将显示在图片的位置。这个属性对于提高网页的可访问性非常重要。

（3）width和height：分别指定图片的宽度和高度。这两个属性可以用来调整图片在网页中的显示大小。

（4）border：设置图片边框的宽度。默认值为0，表示无边框。

（5）align：设置图片的对齐方式。常用的对齐方式有left、right、top、bottom和middle。

2. img src的路径

img src标签中的src属性可以指定图片的路径，包括以下几种情况：

（1）绝对路径：以协议（如http、https）开头，如http://example.com/image.jpg。

（2）相对路径：相对于当前网页的路径，如/image.jpg或../image.jpg。

（3）数据URL：将图片转换为Base64编码，直接嵌入到HTML中，如data:image/jpeg;base64,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
