HTML コンテンツを動的に抽出して、サイトのページにメモを表示しています。問題は、インポートしている HTML コンテンツのスタイル タグの下に CSS が埋め込まれているため、基本的にページのスタイリングが妨げられることです。入ってくるスタイリングが自分のページに作用するのを止める方法はありますか?

例: ページ xyz.css に適用される CSS 罰金があり、プロパティ ....h2{...} を持つ CSS が埋め込まれたサーバーから HTML コンテンツを動的に抽出しているため、これは基本的に外部スタイル シートをオーバーライドします。また、それがどこに影響を与えるかは明らかではありません。

line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">Read the passage given below and sum up in one sentence what you think is the central idea of the passage.</span></b></h1>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">What constitutes obscenity is hazy — by religion, nation, culture or statute. Bertrand Russell goes a step further, arguing that “Obscenity is not a term capable of exact legal definition; in the practice of the Courts, it means ‘anything that shocks the magistrate.’ ” </span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">In the England in which Russell lived, magistrates showed various levels of shock. The British Parliament had passed the Obscene Publications Act in 1857 a few decades before Russell was born, to control obscene literature which was there, “for the single purpose of corrupting the morals of youth and of a nature calculated to shock the common feelings of decency in any well-regulated mind.” Such a broad generalization obviously allowed the moral police to do as they pleased, sometimes absurdly so. For instance, Annie Besant and co-author Charles Bradlaugh were once sentenced to six months in jail for publishing a pamphlet on birth control!</span></p>

<p class="MsoNoSpacing" style="line-height:150%"><b><span style="font-size:14.0pt;

Approach the passage armed with a pencil. Each line should be read asking yourself whether it constitutes an idea or is it a supporting example. </i></span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">If we underline the recurring words in the passage we can easily see that it is about morality. The temptation is to think that the first line gives away the central idea, but that would ignore what is written later. </span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">Let us sum up the ideas that are contained in the passage:</span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">        (<i>i</i>)    Definition of obscenity is hazy</span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">        (<i>ii</i>)    Definition according to British law of 1857</span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">        (<i>iii</i>)   It was used by moral police sometimes to absurd lengths</span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">        (<i>iv</i>)   Example of two people being jailed for talking about birth control</span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">To get to the central idea, we can knock out (ii) and (iv) from the above because these statements do not constitute the idea.</span></p>

<p class="MsoNoSpacing" style="line-height:150%"><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">In the second paragraph, we see some names and an example. We can see that (ii) is supporting (i) and (iv) is supporting (iii). So the central idea must combine statements (i) and (iii). Combining both of them, we can see that the central idea must be something like this: <i>Obscenity is a vague concept that is used by people to control ideas, sometimes to absurd lengths.</i></span></p>

<p class="MsoNoSpacing" style="line-height:150%"><b><span style="font-size:14.0pt;
line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;">What we have learnt:</span></b><span style="font-size:14.0pt;line-height:150%;font-family:&quot;Verdana&quot;,&quot;sans-serif&quot;"> <i>Spotting the central idea requires ignoring details. The central idea should encompass most of the ideas contained in the passage.</i></span></p>

次のように CSS でインライン スタイルをオーバーライドできます(CSS-Tricks から)

為に:

<div style="background: red;">
    The inline styles for this div should make it red.
</div>

使用する:

div[style] {
   background: yellow !important;
}

また

HTML をプルするときにインライン CSS を削除するだけで、それをまったく出力しないでください。CSS をクリーンに保ちます。

!important外部 CSS プロパティに追加できます。プロパティが他のプロパティによってオーバーライドされることはありません。
例えば:
height: 100px !important;

また

このように「CSSのリセット」を使用できます
