如何使用CSS Grid和Javascript制作幻灯片

我正在尝试在网站上创建一个部分,以显示图片和带有标题的段落,具体取决于所选按钮.例如,通过单击午餐,将显示午餐选项,默认的早餐选项将消失.

我一直在使用CSS Grid和javascript来实现这一点,但是,当我单击按钮时,CSS Grid丢失了,我不确定为什么.我正在使用无显示和阻止来显示和隐藏每个部分.

let breakfastButton = document.getElementById('breakfastButton').addEventListener('click', showBreakfast);
let lunchButton = document.getElementById('lunchButton').addEventListener('click', showLunch);


// breakfast
function showBreakfast() {
    document.getElementById('breakfast').style.display = 'block';
    document.getElementById('lunch').style.display = 'none';
}
// lunch
function showLunch() {
    document.getElementById('lunch').style.display = 'block';
    document.getElementById('breakfast').style.display = 'none';
}

    padding: 0;
    margin: 0;
    font-family: 'Roboto', sans-serif;
    margin: 0 auto;
}
.container {
    padding: 1em;
    line-height: 2em;
    max-width: 1200px
}

h2 {
    font-size: 2em;
    font-weight: 300;
    padding: 10px 0
}
p {
    font-size: 22px;
    color: #707070;
    font-weight: 300;
}
:root {
    --main--color: #FF4E4E;
    --main--color--hover: rgb(250, 0, 0);
    --nav--size: 1.5em;
    --footer--size: 1.125em;
}

/* when to eat */
.meals {
    margin-top: 80px;
    text-align: left;
    /* grid */
    display: grid;
    grid-template-columns: repeat(auto-fit, minmax(300px, 1fr));
    grid-gap: 20px;

    display: none;

    padding: 5px;
    text-align: center;
}

.button-basics:hover {
    background-color: var(--main--color--hover);
    cursor: pointer;
}

    width: 100%;

                    exactly. Since you are an athlete training and
                    eating constantly, breakfast can possibly mean
                    twice a day depending on your workouts. However,
                    it is still hugely important to refuel after any
                    early morning workouts with a filling and hearty

            <div class='button-basics'>Snacks</div>
        </div>
    </div>

如您所见,最上面的图像是我想要的最终结果,而最下面的图像是单击午餐按钮时发生的情况,而不是我想要达到的结果.

解决方法:

好的,这应该是非常简单的修复.检查更新的showBreakfast()和showLunch()函数.在显示时,您无需将display属性更改为block即可将其更改为grid,而是保持所需的布局.通过更改显示属性以阻止,您正在放大布局.运行摘要,您将微笑.

let breakfastButton = document.getElementById('breakfastButton').addEventListener('click', showBreakfast);
let lunchButton = document.getElementById('lunchButton').addEventListener('click', showLunch);


// breakfast
function showBreakfast() {
    document.getElementById('breakfast').style.display = 'grid';
    document.getElementById('lunch').style.display = 'none';
}
// lunch
function showLunch() {
    document.getElementById('lunch').style.display = 'grid';
    document.getElementById('breakfast').style.display = 'none';
}
