如何解决如何使用 CSS 或 JavaScript 使文本自动放大到屏幕？
我正在尝试为我的作品集网站使用 CSS 动画效果。在我的名字淡入屏幕后，我想放大特定字母，同时自动放大我的整个名字。
我用 figma 创建了我的名字，并在 HTML 中导入了 SVG。我已经通过将 id 指定给 CSS 并搜索了几个小时来尝试 ::after 函数，但我仍然不知道如何正确执行此操作。
How to make the text content in a div increase and decrease in font size repeatedly?
这是我的代码。

JS
const logo = document.querySelectorAll('#logo path');
for (let i = 0; i < logo.length; i++) {
console.log(`Letter ${i} is ${logo[i].getTotalLength()}`);
}
解决方法
只需将 svg 标签的高度和宽度更改为 auto
<svg id = "logo" width="auto" height="auto" viewBox="0 0 380 53" fill="none" xmlns="http://www.w3.org/2000/svg">
