Bootstrap and Custom CSS

👾Hello Thidar Nyein, Congratulations on completing this challenge!

The html markup for this solution its built entirely with <div>and you can improve it using semantics tags to describe what its inside each block of content. You can replace the <div> that wraps each card with <article> you can wrap the paragraph with the quote with the tag <blockquote> this way you'll wrap each block of element with the best tag in this situation. Pay attention that <div> is only a block element without meaning.

To add the two wave svg background images in the (top/bottom),, the best way is by using background-image to manage it since adding them to the body you make sure it will be under everything, to manage different images inside a single css property as background-image you use the comma inside each properties declare the single modification for each circle separated. See the code below to see your solution with those backgrounds applied:

HERE'S YOUR CODE FIXED:

body {
    background-image: url(./images/bg-pattern-top-desktop.svg), url(./images/bg-pattern-bottom-desktop.svg);
    background-position: left -185px top -236px, right 10px bottom -300px;
    background-repeat: no-repeat;
    background-attachment: fixed;
    background-size: contain, contain;
    background-position: left -185px top -236px, right 10px bottom -300px;
    /* background-repeat: no-repeat; */
    background-attachment: fixed;
    background-size: contain, contain;
    min-height: 100vh;
    /* font-family: 'League Spartan', sans-serif; */
    /* background: url(./images/bg-pattern-top-desktop.svg),url(./images/bg-pattern-bottom-desktop.svg) no-repeat no-repeat; */
    /* color: hsl(300, 43%, 22%); */
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
}

✌️ I hope this helps you and happy coding!
