我正在尝试弄清楚按钮元素是什么导致CSS width 属性被视为按钮的整个宽度,包括填充和边界宽度。 CSS通常有宽度定义内容宽度,填充内框的宽度,以及浏览器(IE,Firefox,Chrome至少在Windows 7上)遵守 div < /强>秒。
在下面的示例中,我将按钮和 div 设置为相似(并且具有悬停效果)但是,对于 div ,我使用宽度来单独指定内容区域的宽度。因此,即使两个按钮整体占据相同的宽度,按钮的CSS宽度为190px,而CSS宽度为152px(或悬停时为150px)。
(结果是否与 display:inline-block 相同,我添加到CSS div 以尝试匹配浏览器的显示按钮的属性。)
结果:
任何见解?

您需要重置按钮css样式,默认情况下为每个浏览器以不同的方式定义。
/*fix for Firefox */
button::-moz-focus-inner{
border: 0;
padding: 0;
}
/*reset button CSS */
button{
margin: 0;
padding: 0;
border: none;
font: inherit;
box-sizing: border-box;
}
/*fix for Firefox */
button::-moz-focus-inner {
border: 0;
padding: 0;
}
/*reset button CSS */
button {
margin: 0;
padding: 0;
border: none;
font: inherit;
box-sizing: border-box;
}
.xbutton {
width: 190px;
text-align: left;
background: -webkit-linear-gradient(#eaf2f5, #e0eaee);
