html - How do I put a button to the bottom of a box? - Stack Overflow|Programmer puzzle solving

I have recently started using html in order to create a website for my project. I have planned on making this website that contains the intro page, that has a button, revealing further contents. This is my current html code:

body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 0;
    background-color: #24576c;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
}

#box {
    width: 80%;
    background-color: #D5C6EE;
    border: 1px solid #ccc;
    border-radius: 10px;
    padding: 20px;
    box-shadow: 0px 4px 8px rgba(0, 0, 0, 0.1);
    display: flex;
    flex-direction: column;
    justify-content: space-between;
    height: auto;
    
}

#title {
    text-align: center;
    margin-bottom: 10px;
    font-weight: bold;
}

#underline {
    border: none;
    height: 2px;
    background-color: #131E62;
    width: 100%;
    margin-bottom: 20px;
}

#content {
    font-size: 20px;
    text-align: justify;
    line-height: 1.6;
    flex-grow: 1;
}

.button {
    display: flex;
    justify-content: center;
    margin-top: 20px;
}

#know-more-button {
    text-decoration: none;
    background-color: #AABFEF;
    color: white;
    padding: 10px 20px;
    border: none;
    border-radius: 5px;
    font-size: 16px;
    cursor: pointer;

}

#know-more-button:hover {
    background-color: #0056b3;
}

body {
    background-image: url(".jpg!d"); 
    background-size: cover; 
    background-repeat: no-repeat; 
    background-position: center; 
    height: 100vh;
    margin: 0; 
}

        <a id="know-more-button" href="secondpage.html">Know More</a>
    </div>

</body>
</html>

Everything turns out to be good, except for the "know more button" that I expected to be in the bottom of the box. (shown below)

I would like to ask for your help in order to make the button appear at the right place. :)

The div of your button is not nested inside the box div. This means it will appear outside of the box.

It should look something like this:

    <div id="box">
        <h1 id="title">Brief Introduction</h1>
        <hr id="underline">
        <div id="content">
            <p>content</p>
        </div>
        <br>
        <div id="button-container" class="button">
            <a id="know-more-button" href="secondpage.html">Know More</a>
        </div>
    </div>
