CSS The ::first-letter pseudo-element in CSS can select and style the first letter of an element. We can use this pseudo-element to select the first letter of the asterisk in the p tag and set its color.

The sample code is as follows:

p::first-letter {
color: red;
}

In the above code, we set the color of the first letter of the asterisk in the p tag to red.

If there are multiple p tags on a page, we can add a specific class name to the p tag that needs to set the color of the first letter of the asterisk and set the style in CSS using the class name selector.

The sample code is as follows:

<p class="red-asterix">This is a paragraph with an asterix*.</p> 
<p>This is a normal paragraph without an asterix.</p> 

.red-asterix::first-letter {
color: red; 
} 

In the above code, we add a class name “red-asterix” to the p tag containing the asterisk and set the color of the first letter of the class name to red.

3. Dynamically Setting Colors with JavaScript

If we need to dynamically set the color of the first letter of the asterisk based on specific conditions, we can use JavaScript to achieve this.

The sample code is as follows:

<p id="dynamic-color">This is a paragraph with an asterix*.</p> 
<p>This is a normal paragraph without an asterix.</p> 

const paragraph = document.getElementById('dynamic-color'); 
const firstLetter = paragraph.innerHTML[paragraph.innerHTML.indexOf('*') + 1]; 

if (firstLetter === '*') { 
paragraph.style.color = 'blue'; 
} 

In the above code, we first get the p tag with the asterisk and use JavaScript retrieves the first letter of the asterisk. Then, we check whether the first letter is an asterisk and set the color to blue if the condition is met.

The sample code is as follows:

p::first-letter {
color: red;
font-size: 24px;
font-weight: bold;
font-style: italic;
}
