html - 步骤进度条 - 进度编号框之间的线

Question

我想让步骤之间的线条更长或者可能粘在盒子上。我尝试更改此 css .bullet.completed::after 但它不起作用。我将宽度设置为 100% 的原因是因为我希望它能够响应。

我已在此处附加了片段。有人可以帮我解决这个问题吗？提前致谢!

const previousBtn = document.getElementById('previousBtn');
const nextBtn = document.getElementById('nextBtn');
const finishBtn = document.getElementById('finishBtn');
const content = document.getElementById('content');
const bullets = [...document.querySelectorAll('.bullet')];

const MAX_STEPS = 4;
let currentStep = 1;

nextBtn.addEventListener('click', () => {
  bullets[currentStep - 1].classList.add('completed');
  currentStep += 1;
  previousBtn.disabled = false;
  if (currentStep === MAX_STEPS) {
    nextBtn.disabled = true;
    finishBtn.disabled = false;
  }
  content.innerText = `Step Number ${currentStep}`;
});


previousBtn.addEventListener('click', () => {
  bullets[currentStep - 2].classList.remove('completed');
  currentStep -= 1;
  nextBtn.disabled = false;
  finishBtn.disabled = true;
  if (currentStep === 1) {
    previousBtn.disabled = true;
  }
  content.innerText = `Step Number ${currentStep}`;
});

finishBtn.addEventListener('click', () => {
  location.reload();
});

我使用 CSS calc 函数来找到行长度的最佳位置。计算:宽度:calc(133% - 21px);。

计算的21px部分是:

• 数字宽度的一半 (20px/2 = 10)
• 4px 表示相邻框的边框
• 7px 左边距将线移离框的中心。

我还不确定为什么 133% 有效 🤔。此外，我从 .bullet 类中删除了 position:relative 并将其移至 .step 父级。

const previousBtn = document.getElementById('previousBtn');
const nextBtn = document.getElementById('nextBtn');
const finishBtn = document.getElementById('finishBtn');
const content = document.getElementById('content');
const bullets = [...document.querySelectorAll('.bullet')];

const MAX_STEPS = 4;
let currentStep = 1;

nextBtn.addEventListener('click', () => {
  bullets[currentStep - 1].classList.add('completed');
  currentStep += 1;
  previousBtn.disabled = false;
  if (currentStep === MAX_STEPS) {
    nextBtn.disabled = true;
    finishBtn.disabled = false;
  }
  content.innerText = `Step Number ${currentStep}`;
});


previousBtn.addEventListener('click', () => {
  bullets[currentStep - 2].classList.remove('completed');
  currentStep -= 1;
  nextBtn.disabled = false;
  finishBtn.disabled = true;
  if (currentStep === 1) {
    previousBtn.disabled = true;
  }
  content.innerText = `Step Number ${currentStep}`;
});

finishBtn.addEventListener('click', () => {
  location.reload();
});

#stepProgressBar {
  display: flex;
  justify-content: space-between;
  align-items: flex-end;
  width: 90%;
  margin: 0 auto;
  margin-bottom: 40px;
}

.step {
  text-align: center;
  width: 20%;
  position: relative;
}

.step-text {
  margin-bottom: 10px;
  color: #000;

.bullet {

  width: 20px;

  line-height: 20px;
}

.bullet.completed {
  color: white;
  background-color: #000;
}

.bullet.completed::after {
  content: '';
  position: absolute;
  bottom: 10px;
  height: 1px;
  width: calc(133% - 21px);
  background-color: #000;
  margin-left: 7px;
