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';

<h2>Breakfast</h2>
<p>The most important meal of the day, right? Not
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
meal

</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.
