Question

我是前端Web编码的新手，我想建立一个样机网站以加快学习过程。我想使登录部分与页面中间对齐，我发现了一些使用flex-grow的教程，因此可以随尺寸缩放，但这是我得到的：

我做错了什么？

（我只发布了一些代码片段，我认为这不会使事情复杂化）

.sign-in {
  display: flex;
  justify-content: space-between;
  align-items: center;
  flex-grow: 1;
  **<THE PART WHERE THE PROBLEM ARISES>**
}

.sign-in-text {
  display: flex;
  align-items: left;
  flex-direction: column;
  font-size: 3.5em;
  font-weight: bold;
  margin: 0;
  padding: 0;
}

.not-sign-in-text {
  font-size: 2rem;
  padding: 0;
  margin: 0;
}

.miss-you {
  font-size: 1.5rem;
  font-weight: 500;
}

.sign-in-form {
  display: flex;
  align-items: left;
  flex-direction: column;
}

感谢您的帮助！

Answer 1

尝试以下方法：

.sign-in {
    display:flex;
    justify-content: center;
    flex-direction: column;
    align-items: center;
}

Answer 2

根据您的代码片段，我认为这是您所需要的吗？

.sign-in {
  display: flex;
  justify-content: space-between;
  align-items: center;
  display: flex;
  flex-direction: row;
  width: 100%;
}

#leftContent {
  text-align: right;
  width: 50%;
}

#rightContent {
  text-align: left;
  width: 50%;
  margin-left: 10%;
}

.sign-in-text {
  display: flex;
  flex-direction: column;
  font-size: 3.5em;
  font-weight: bold;
  margin: 0;
  padding: 0;
}

.not-sign-in-text {
  font-size: 2rem;
  padding: 0;
  margin: 0;
}

.miss-you {
  font-size: 1.5rem;
  font-weight: 500;
}

.sign-in-form {
  display: flex;
  align-items: left;
  flex-direction: column;
}

                                </button>
          </div>
        </form>
      </div>

flex-grow不起作用，我做错了什么？
