Let's say the HTML is defined as
<div>
<div class="runtime"> Some Important Text.Insert "Important" Before This </div>
<div class="normal"> General Text </div>
</div>
Typically, the output would be
Some Important Text.Insert "Important" Before This
General Text
However, upon rendering, we expect to see
Important Generated Content
Some Important Text.Insert "Important" Before This
General Text
I am specifically looking for a CSS solution.
Are you seeking this information?
.runtime:before{
content: "Important Generated Content";
font-weight: bold;
display: block;
}
Avoid directly altering the code to prevent plagiarism, but consider adding margin-bottom as recommended by other responses.
You may wonder, is there an after as well as a before?
Indeed, there is!
Try out variations like
.importantStuff:after{
content: "!!!!!";
}
This will append exclamation marks to the end of elements with the importantStuff class
Keep in mind, each element can have only one before and one after, so use them judiciously. Have fun experimenting with CSS.
.runtime:after {
content: "Crucial Generated Material";
font-weight: bold;
display: block;
margin-bottom: 20px;
}

To enhance your design, consider utilizing the pseudo-class :before in conjunction with the content property.
.runtime:before {
content:"Don't miss this!";
font-weight: bold;
}

For further insights and a deeper understanding of this property, take a look at this informative guide. It provides information on special characters and highlights that they are not able to be transitioned or animated.
Implementing pseudo-class in CSS
.container:before{
content:"Dynamic Content here";
font-style:italic;
}
Another option to consider is using jquery.
$('.runtime').before('<p>Test</p>');
When it comes to changing the content on a page, CSS is not the tool for the job – JavaScript is what you need. However, there is a workaround using the :before pseudo-element in CSS to create a 'fake' element and add content to it using the content rule.
.runtime:before{
content: "Important Generated Content";
font-weight: bold;
}
Some individuals may encounter challenges with this approach as CSS was originally designed to style elements, not insert text. While CSS provides a more convenient solution compared to JavaScript, there is a significant drawback – users relying on assistive technologies may experience difficulties as discussed in this blog post, as the generated content within pseudo-elements will not be accessible.
An alternative method involves utilizing JavaScript to generate the label. The following example demonstrates how to add a <p> element above all elements with the class .important.
HTML
<div class="important">I am very important</div>
<div>I am not</div>
<div class="important">I am very important</div>
jQuery
$(document).ready(function () {
$('.important').before('<div class="important-notice">Important!</div>');
});
