我要做一个功能，html中有一个横向长条，内部从左到右是一张logo图片、几个字，一个展开按钮，并且右侧有一个三角图标。点击展开按钮时，横条下方出现一个文字容器，高度根据文字内容显示。文字不直接展示，而是从头到尾一个字一个字的出现，间隔100ms。写出对应的html代码和js代码

HTML代码：

<div class="horizontal-bar">
    <div class="logo">
        <img src="logo.png" alt="Logo">
    </div>
    <div class="text">
        <p>这是一些文本</p>
    </div>
    <div class="expand-btn">
        展开
        <i class="triangle-icon"></i>
    </div>
</div>
<div class="text-container"></div>

CSS代码：

.horizontal-bar {
    display: flex;
    align-items: center;
    height: 50px;
    background-color: #F5F5F5;
    padding: 0 20px;
    position: relative;
}

.logo {
    margin-right: 10px;
}

.text {
    margin-right: 10px;
}

.expand-btn {
    display: flex;
    align-items: center;
    justify-content: center;
    color: #333;
    cursor: pointer;
}

.triangle-icon {
    display: inline-block;
    width: 0;
    height: 0;
    border-style: solid;
    border-width: 5px 0 5px 8.7px;
    border-color: transparent transparent transparent #333;
    margin-left: 5px;
}

.text-container {
    display: none;
    padding: 10px;
    background-color: #FFF;
    position: absolute;
    left: 0;
    bottom: -1px;
    width: 100%;
    z-index: 999;
}

JavaScript代码：

const expandBtn = document.querySelector('.expand-btn');
const textContainer = document.querySelector('.text-container');
const text = document.querySelector('.text p').innerText;
let index = 0;

expandBtn.addEventListener('click', () => {
    textContainer.style.display = 'block';
    const interval = setInterval(() => {
        if (index < text.length) {
            textContainer.innerText += text.charAt(index);
            index++;
        } else {
            clearInterval(interval);
        }
    }, 100);
});

HTML代码：

<div class="horizontal-bar">
    <div class="logo">
        <img src="logo.png" alt="Logo">
    </div>
    <div class="text">
        <p>这是一些文本</p>
    </div>
    <div class="expand-btn">
        展开
        <i class="triangle-icon"></i>
    </div>
</div>
<div class="text-container"></div>

.logo {
