Max-height of Card component

Sorry, this is probably a very basic functionality, but im new to bootstrap, already tried searching elswhere, but didnt find a clean bootstrap way to solve this.

Expected behavior

Im using boostrap's Card Deck. I want to limit the amount of text inside

element of the Card to a specific amount of lines/characters. If amount is surpassed, show "..." after the limit Actual behavior

What I've found is advice to add "text-truncate" class to the

element. It does limit the text but sets limit to one line of text. How to specify amount of lines/characters for the limit ?

Resources (screenshots, code snippets etc.)

    <div class="col mb-4 " th:each="tempCard : ${cards}">
        <div class="card h-100 my-card-style">
            <img th:src="@{/images/no-image.png}" class="card-img-top" alt="No Image" style="max-width:90%;margin-left: auto;margin-right: auto;">
            <div class="card-body">
                <h5 class="card-title" th:text="${tempCard.title}">Card title</h5>
                <p class="card-text text-truncate" th:text="${tempCard.text}">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
                <a href="#" class="btn btn-primary">Go somewhere</a>
            </div>
        </div>
    </div>

this html contains some thymeleaf (th:...), you can ignore it. Notice the text-truncate in

As you can see, the text-truncate limits text to only ONE line, i would like to control the limit size.

Thank you
