Stylize the ordered list and unordered list

Hi there,

the Site you provided a link for uses this CSS:

.entry-content ol {
    counter-reset: li;
}

ol {
    list-style: decimal;
}

.entry-content ol li {
    position: relative;
    margin: 0 0 .5rem 1.03rem;
    padding: 4px 1.1rem .3rem 1.5rem;
    list-style: none;
    border-left: .5px solid #073042;
}

.entry-content ol>li:before {
    content: counter(li);
    counter-increment: li;
    position: absolute;
    top: 0;
    left: -1.2em;
    box-sizing: border-box;
    margin-right: 8px;
    display: block;
    font-size: .9rem;
    padding: 7px;
    width: 2.1rem;
    height: 2.1rem;
    line-height: 1.3;
    text-align: center;
    font-weight: 500;
    border: .5px solid #15C77C;
    background: #15C77C;
    color: #fff;
    border-radius: 999em;
}

Thanks, David it's working, now I want same vertical line for the unordered list as well. How to achieve that

Try replacing ol in David's code with ul
