我明白了:
为什么标签/div(我都试过了)不居中？
最佳答案
改变:
<div style="text-align:center; color: #4E1329; font-size: smaller; float:none">
you can search by acc no and username
</div>
到
<div style="width: 100%; text-align:center; color: #4E1329; font-size: smaller; display:inline;">
you can search by acc no and username
</div>
注意:您可能还想考虑使用 CSS 类而不是内联样式。
编辑:好的，在看到您的编辑后，您的类 block 需要设置宽度。为了使文本能够居中，它需要 100% 宽度。为了使 100% 宽度起作用，您需要一个具有宽度的父对象。如果 block 有宽度，请发布它的 CSS。
编辑 - 最终修订:
display:inline 现在混淆了它。这和 float:none; 需要删除。
<div style="width: 100%; text-align:center; color: #4E1329; font-size: smaller;">
you can search by acc no and username
</div>
