Can't restrict the CSS animation on a particul

Question

Somehow I can't make this animation restricted to only one particular section of the webpage. I don't want it to displayed on the whole background, just want to keep it fixed into one div.

Here is the html code

<div class="sp-container">
<div class="sp-content">
    <div class="sp-globe"></div>
    <h2 class="frame-1">Reliable</h2>
    <h2 class="frame-2">Fast</h2>
    <h2 class="frame-3">Responsive</h2>
    <h2 class="frame-4">Beautiful</h2>
    <h2 class="frame-5">
        <span>bla</span>
        <span>bla</span>
        <span>bla</span>
    </h2>
    <a class="sp-circle-link" > Merry go round</a>
</div>

here is the css

This animation was not created by me. I know it's something silly.

Answer 1

It is fixed to one div. It's fixed to sp-container.

If you are trying to make only one section animated, you can wrap that section in sp-container and remove sp-container from the rest of your content. If sp-container is used for something other than animation you can remove just the animation elements from sp-container and add them back.

This is your code with animation removed from sp-container and added to specific elements if you want animation on specific content you can use either :

<div class="animation-fade"></div>
<div class="animation-blur"></div>

Also note, you have animation delay on some elements like h2 when its wrapped in sp-container. So if you are not going to use animation with your h2 tags I suggest removing the animation delay.
