Display an HTML code snippet on the webpage

I'm facing a situation that has been discussed before on this platform. However, I want to present my problem in a different light. I am working with PHP and need to display an HTML string from the database on my webpage. The issue is that the CSS applied to the page is very generic, causing it to also affect the styling of the HTML string. I specifically want the content to appear without any styling at all. Despite searching online, all I found was information about using the "not" selector in CSS. Is there a way to target a single element on my HTML page that will not be affected by the general styling/CSS? While the "not" selector targets all elements except the one specified, I actually need the opposite effect.

<style>
.div-class p{font-weight: bold;}
.div-class p:not(.no-style){font-weight: normal;}
</style>

<div class="div-class">
<p>This should be bold.</p>
<p class="no-style">This should not be bold.</p>
</div>

My objective is for the "p" element with the "no-style" class to have a normal font weight, whereas currently it is the reverse. I hope I have explained myself clearly.

Thank you,

htmlcss

Answer №1

If you want to display your script output within a specific div, simply assign it an id or class and apply a CSS reset to that div. There are many different types of CSS resets to choose from.

Just my opinion, but I don't believe there is a CSS rule that can completely disable all styles for certain elements.

Another option is to create an empty iframe with a source attribute of "about:blank", then use JavaScript to insert your content into the iframe.

Answer №2

<style>
.div-class p
{
font-weight: bold;
}
.div-class p.no-style
{
font-weight: normal;
}
</style>

<div class="div-class">
<p>This text will appear in a bold font.</p>
<p class="no-style">This text will not appear in a bold font.    </p>
</div>

It is important to note that you cannot completely avoid inheriting styles. One workaround is using the "not" selector in CSS:

<style>
p:not(.unstyled){
font-weight : bold;
}
</style>


<p> This text should be bold </p>
<p class='unstyled'> This text should not be bold </p>

In this case, add the "unstyled" class to all PHP-generated content and use ":not(.styled)" in your CSS declarations.

An alternative solution is to redefine every style in your CSS to match the original response provided above.

Keep in mind the compatibility of the "not" selector across different web browsers.

Answer №3

there is a straightforward method to override the styles that have been applied by using !important

for instance

p{
font-weight:bold;
}

will not take effect if you include 

.nostyle
{
font-weight:normal !important;
}
