Css – Vertically center rotated text with CSS

centeringcssvertical-alignmentvertical-text

I have the following HTML:

<div class="outer">
    <div class="inner rotate">Centered?</div>
</div>

div.outer is a narrow vertical strip. div.inner is rotated 90 degrees. I would like the text "Centered?" to appear centered in its container div. I do not know the size of either div in advance.

This comes close: http://jsfiddle.net/CCMyf/2/. You can see from the jsfiddle that the text is vertically centered before the transform: rotate(-90deg) style is applied, but is somewhat offset after. This is particularly noticeable when div.outer is short.

Is it possible to center this text vertically without knowing any of the sizes in advance? I haven't found any values of transform-origin that solve this problem.

The key is to set position top and left to 50% and then transformX and transformY to -50%.

.inner {
    position: absolute;
    top: 50%;
    left: 50%;
}

.rotate {  
    transform:  translateX(-50%) translateY(-50%) rotate(-90deg);
}

Html – How to horizontally center an element

You can apply this CSS to the inner <div>:

#inner {
  width: 50%;
  margin: 0 auto;
}

Of course, you don't have to set the width to 50%. Any width less than the containing <div> will work. The margin: 0 auto is what does the actual centering.

If you are targeting Internet Explorer 8 (and later), it might be better to have this instead:

#inner {
  display: table;
  margin: 0 auto;
}

It will make the inner element center horizontally and it works without setting a specific width.

Working example here:

#inner {
  display: table;
  margin: 0 auto;
  border: 1px solid black;
}

#outer {
  border: 1px solid red;
  width:100%
}

<div id="outer">
  <div id="inner">Foo foo</div>
</div>

EDIT

With flexbox it is very easy to style the div horizontally and vertically centered.

#inner {  
  border: 1px solid black;
}

#outer {
  border: 1px solid red;
  width:100%;
  display: flex;
  justify-content: center;
}

<div id="outer">
  <div id="inner">Foo foo</div>
</div>

To align the div vertically centered, use the property align-items: center.

Html – Set cellpadding and cellspacing in CSS

Basics

For controlling "cellpadding" in CSS, you can simply use padding on table cells. E.g. for 10px of "cellpadding":

td { 
    padding: 10px;
}

For "cellspacing", you can apply the border-spacing CSS property to your table. E.g. for 10px of "cellspacing":

table { 
    border-spacing: 10px;
    border-collapse: separate;
}

This property will even allow separate horizontal and vertical spacing, something you couldn't do with old-school "cellspacing".

Issues in IE ≤ 7

This will work in almost all popular browsers except for Internet Explorer up through Internet Explorer 7, where you're almost out of luck. I say "almost" because these browsers still support the border-collapse property, which merges the borders of adjoining table cells. If you're trying to eliminate cellspacing (that is, cellspacing="0") then border-collapse:collapse should have the same effect: no space between table cells. This support is buggy, though, as it does not override an existing cellspacing HTML attribute on the table element.

In short: for non-Internet Explorer 5-7 browsers, border-spacing handles you. For Internet Explorer, if your situation is just right (you want 0 cellspacing and your table doesn't have it defined already), you can use border-collapse:collapse.

table { 
    border-spacing: 0;
    border-collapse: collapse;
}

Note: For a great overview of CSS properties that one can apply to tables and for which browsers, see this fantastic Quirksmode page.
