我正在创建一个使用许多自定义样式的 Javascript 小部件。当用户将小部件放在他的页面上时，用户的页面总是会影响小部件的样式。有没有办法防止这种情况？

例如，如果我的小部件中有一个输入框：

<input id="#special-input" />

并且用户具有覆盖输入的样式：

input { width: 500px; }

然后，用户的页面会覆盖输入框的宽度。用户可以通过多种方式更改小部件的样式，我无法解释所有这些方式。例如，对于输入，我必须考虑边框、阴影、宽度、高度等以及用户可以设置页面样式并影响我的小部件的任何其他方式。

要背负我上面的评论，您可以执行以下操作。（完全未经测试并迅速组合在一起）这使用 Jquery，但我相信如果您使用另一个库或纯 JS，您可以弄清楚如何修改它。

var allStyles = ["azimuth","background","backgroundAttachment","backgroundColor","backgroundImage","backgroundPosition","backgroundRepeat","border","borderBottom","borderBottomColor","borderBottomStyle","borderBottomWidth","borderCollapse","borderColor","borderLeft","borderLeftColor","borderLeftStyle","borderLeftWidth","borderRight","borderRightColor","borderRightStyle","borderRightWidth","borderSpacing","borderStyle","borderTop","borderTopColor","borderTopStyle","borderTopWidth","borderWidth","bottom","captionSide","clear","clip","color","content","counterIncrement","counterReset","cssFloat","cue","cueAfter","cueBefore","cursor","direction","display","elevation","emptyCells","font","fontFamily","fontSize","fontSizeAdjust","fontStretch","fontStyle","fontVariant","fontWeight","height","left","letterSpacing","lineHeight","listStyle","listStyleImage","listStylePosition","listStyleType","margin","marginBottom","marginLeft","marginRight","marginTop","markerOffset","marks","maxHeight","maxWidth","minHeight","minWidth","orphans","outline","outlineColor","outlineStyle","outlineWidth","overflow","padding","paddingBottom","paddingLeft","paddingRight","paddingTop","page","pageBreakAfter","pageBreakBefore","pageBreakInside","pause","pauseAfter","pauseBefore","pitch","pitchRange","playDuring","position","quotes","richness","right","size","speak","speakHeader","speakNumeral","speakPunctuation","speechRate","stress","tableLayout","textAlign","textDecoration","textIndent","textShadow","textTransform","top","unicodeBidi","verticalAlign","visibility","voiceFamily","volume","whiteSpace","widows","width","wordSpacing","zIndex"];

    $.each(allStyles, function(key, value){
        if ($this.css(value) !== undefined){
            $this.css(key, "")
        }
    });

注意我上面的帖子是根据另一个主题的这个答案修改的。只是想感谢@Matrym... getComputedStyle (or) $.css(map) <-- 获取每个样式声明
