的CSS:
.sat{
color: red;
}
.sun{
color: red;
}
"1" {
color: blue;
}
目前我遇到了问题,因为我需要在我的html代码中专门找到数字1,然后通过css将其更改为红色而不使其他任何其他红色并且不编辑html文件,因为html文件将不断通过我的python脚本更新和重置。

您已经在HTML中添加了一个类.one
,因此您需要做的只是添加:
.one{color:blue;}
你的CSS中的
编辑:
如果.one
仅用于包含&#34; 1&#34;的元素,我刚刚说过的话就有意义了。但看到你的HTML看起来如此

它将突出显示其中包含1的td。
答案 3 :(得分:0)
"1" { color: blue; }
无效CSS。 CSS选择器不能以一个数字开头,其次,它们永远不会用引号括起来。
正如其他答案所提到的那样,您可以通过为元素提供“one”类并相应地调整CSS来解决此问题。我不会在这里发布CSS,因为这里有3个答案已经显示出来了。
但是,您的问题让我相信这不一定是您可以选择的选项。问题是这可以实现,但不能仅靠CSS。您将不得不使用脚本来定位这些元素。为了完整答案,您可以使用以下jQuery脚本来实现此目的:
<script>
$('td').each(function(){ //loop through each td
if($(this).html() == '1') { //if the content of the td is exactly "1" (without quotes)
$(this).css({'color':'blue'}); //change the CSS rule to have color:blue;
}
});
</script>
