问题描述

Chrome 和其他浏览器中,我的下拉菜单显示为 /i.stack.imgur.com/OihyJ.pngalt =

然而,在 Firefox 中,不需要的虚线行:

按钮和输入元素的不需要的Firefox虚线删除了这些CSS语句:

  button: -  moz-focus-inner {border:0; } 
input :: - moz-focus-inner {border:0; }

所以我认为这些可以用于select / option元素,但是它们不会:

  select ::  -  moz-focus-inner {border:0; } 
选项:: - moz-focus-inner {border:0; }

如何删除此下拉列表中的虚线,以便在Chrome中显示和其他浏览器?

附录



这些都不起作用:

  select ::  -  moz-focus-inner {border:0;大纲:0} 
选项:: - moz-focus-inner {border:0;大纲:0}

也不是这些:

  select {outline:0; } 
选项{outline:0; }

也没有这些:

  select {outline:none; } 
选项{outline:none; James Broad的答案是近乎完美的,但是阴影文本的选项项目看起来很丑。这是完美的作品:

pre $ select:-moz-focusring {
color:transparent;
text-shadow:0 0 0#000; / *您的正常文字颜色在这里* /
}
选择:-moz-focusring * {
color:#000; / *您的正常文字颜色在这里* /
text-shadow:none;
}


In Chrome and other browsers my dropdown looks fine:

However, in Firefox it has unwanted dotted lines:

I have successfully removed the unwanted Firefox dotted lines for buttons and input elements with these CSS statements:

button::-moz-focus-inner { border: 0; }
input::-moz-focus-inner { border: 0; }

so I thought these would work for the select/option elements, but they don't:

select::-moz-focus-inner { border: 0; }
option::-moz-focus-inner { border: 0; }

How can I remove the dotted lines in this dropdown so that it appears as in Chrome and other browsers?

Addendum

These don't work either:

select::-moz-focus-inner { border: 0; outline: 0 }
option::-moz-focus-inner { border: 0; outline: 0 }

nor these:

select { outline: 0; }
option { outline: 0; }

nor these:

select { outline: none; }
option { outline: none; }

解决方案

James Broad's answer is nearly perfect, but the "shadow-only" text for the option items looks ugly. This is what works perfectly for me:

select:-moz-focusring {
  color:transparent;
  text-shadow:0 0 0 #000; /* your normal text color here */
}
select:-moz-focusring * {
  color:#000; /* your normal text color here */
  text-shadow:none;
}
