如果您希望頂部文本根據父元素的寬度（已被.second-text-middle內部文本擴展）擴展，您可以使用簡單的 JavaScript。
在這里，我們可以檢查 和 的寬度，#n1并.first-text-middle增加 的font size: n%;，#n1直到它適合父級。
fitWidth();
window.addEventListener("resize", function() {
fitWidth();
});
function fitWidth() {
let first = document.querySelector('.first-text-middle');
let firstText = document.getElementById('n1');
let textSize = 100; // we will use it like a base 100% font-size later
// set font size to '#n1'
firstText.style.cssText = 'font-size:' + textSize + '%';
while (first.clientWidth - 2 >= firstText.offsetWidth) {
textSize = textSize + 1; //increments font size by 1% each loop
firstText.style.cssText = 'font-size:' + textSize + '%';
// basically in DOM you see only result of the very last loop of this 'while' statment
}
