👋 Hey there Docebo Community, and happy Friday!

Check out this awesome post on Medium:

🔗 Fantastic CSS border animation

This post popped up in my inbox today and I found it extremely interesting. I’m not quite savvy enough with CSS to understand everything this article covers in detail, but we have some experts in this community (I’m looking at you @gstager @Bfarkas @nick.tosto) who I’m sure could do some pretty awesome things in their platforms with some of the code shared in the post.

Here’s a snippet I found to be really cool:

Border length changes

div {
    position: relative;
    border: 1px solid #03A9F3;

    &::before,
    &::after {
        content: "";
        position: absolute;
        width: 20px;
        height: 20px;
    }

    &::before {
        top: -5px;
        left: -5px;
        border-top: 1px solid var(--borderColor);
        border-left: 1px solid var(--borderColor);
    }

    &::after {
        right: -5px;
        bottom: -5px;
        border-bottom: 1px solid var(--borderColor);
        border-right: 1px solid var(--borderColor);
    }

    &:hover::before,
    &:hover::after {
        width: calc(100% + 9px);
        height: calc(100% + 9px);
    }
}
