Can CSS Transitions Create a Fade-In Effect for Text on Page Load?

Using CSS for a Fade-In Effect on Page Load

Can CSS transitions be effectively employed to make a text paragraph fade in as the page loads?

Certainly. CSS transitions offer a simple solution for this visual effect. Consider the following steps:

Step 1: Define CSS

Create a CSS rule that specifies the initial visibility of the text paragraph:

#test p {
    opacity: 0;
    margin-top: 25px;
    font-size: 21px;
    text-align: center;
    transition: opacity 2s ease-in;  
}

• opacity: 0 makes the paragraph initially invisible by setting its opacity to 0.
• margin-top: 25px and font-size: 21px adjust its styling.
• text-align: center centers the text.
• transition: opacity 2s ease-in; sets the duration and easing effect for the transition.

Step 2: Toggle Opacity

To trigger the transition, you'll need to change the opacity of the paragraph once the page loads. This can be achieved using:

Method 1: CSS Animations (self-invoking)

@keyframes fadein {
    from { opacity: 0; }
    to   { opacity: 1; }
}

#test p { ... } /* Apply the fadein animation */

Method 2: jQuery or Plain JavaScript

• jQuery: $("#test p").addClass("load");
• Plain JavaScript: document.getElementById("test").children[0].className = " load";

Step 3: Adjust CSS for the "load" class

With the class added, define the style for the paragraph when it's in "load" state:

#test p.load {
    opacity: 1;
}

Alternatively, you could use JavaScript to change the opacity directly.
