This question already has answers here: Why is the <center> tag deprecated in HTML? (13 answers) Closed 10 years ago.

I read that the <center> tag is deprecated, however I cannot find any real equ开发者_C百科ivalent to it in CSS. text-align works for text but not other elements, and auto margins only work if you know the width of the container (so not a solution if you don't know the width in advance). So is there any real equivalent to this <center> tag?

text-align should work for other kinds of elements. Does this work?

.center { margin: auto; text-align: center; }

Edit Three Years Later :-D

margin: auto; also makes the top and bottom margins "auto". That might not be what you want. Alternatively you could have something like:

.center {
  margin-left: auto;
  margin-right: auto;
  margin-top: 3px;
  margin-bottom: 3px;
  text-align: center;
  display: flex;
  justify-content: center;
}

This particular example will center the text horizontally while hardwiring the upper and lower margins to 3 pixels.

One can also say something like margin: 3px auto 3px auto; but I prefer spelling out the directions explicitly, as I can never quite remember what the order of the parameters are if I put them all on the one margin: setting.

There is a difference:

<center>
  <span>Works</span>
</center>

<span style="margin: auto; text-align: center;"> And this is broken</span>

<div style="margin: auto; text-align: center;">But this works works</div>
