I have this HTML:
<section id="about" class="about section light-background">

            <div class="container">
                <div class="content">
                    <div class="row justify-content-center">

                                <div class="img">

                                </div>
                            </div>
                        </div>

                        <div class="offset-md-0 offset-lg-1 col-sm-12 col-md-5 col-lg-5 col-xl-4 aos-init aos-animate" data-aos="fade-up">

                </div>
            </div>
        </section>

And following CSS:
.about .content {
    background-color: var(--surface-color);
    padding-top: 50px;
    padding-bottom: 50px;
}

.about .content-subtitle {
    font-size: 15px;
    margin-bottom: 10px;
    display: block;
    color: var(--default-color);
}

.about .content-title {
    color: var(--heading-color);
    font-size: 22px;
    margin-bottom: 30px;
}

.about p {
    line-height: 1.7;
    color: var(--default-color);
}

.about .btn-get-started {
    background-color: var(--accent-color);
    color: var(--contrast-color);
    border-radius: 30px;
    padding: 8px 30px;
    border: 2px solid transparent;
    transition: 0.3s all ease-in-out;
    font-size: 14px;
}

.about .btn-get-started:hover {
    border-color: var(--accent-color);
    background-color: transparent;
    color: var(--accent-color);
}

.about .lead {
    line-height: 1.6;
    font-size: 18px;
    font-weight: normal;
    color: var(--default-color);
}

.about .img-wrap .img {
    overflow: hidden;
    max-height: 540px;
}

.about .img-wrap .img video {
    max-width: 100%;
}


Now, I want 'Laxmi | Saraswati | Durga' text written vertically (rotated at -90 degrees) on the left of .content element.
