现在，当我尝试在我自己的 index.php 上实现这个脚本时。 但是搜索按钮的高度 38 和宽度 78 少了 2 个像素。而 css 告诉它是 40 和 80。所以我认为它可能会因为我在我的网站上使用的其他 css 而产生这种冲突。我试图通过在元素上使用此代码来重置 css，

但遗憾的是，重置所有 css 并不能解决问题。我知道一种解决方法是在宽度和高度上都增加 2 个像素，但我宁愿找出它具有这种行为的原因。
希望大家帮忙。
您真诚的，

图 1 为什么这些不同？ /image/9dhyW.png 图 2 为什么这些不同？ /image/XA6jc.png
最佳答案
有一个 border: 1px solid #444; 设置和 box-sizing: border-box 将边框包含在定义的宽度中。因此，如果宽度为 80px，则实际内容的宽度将减少 2 x 1px(两侧)(= 78px)。高度相同。
