CSS STYLE TABLE CELL VERTICAL ALIGNMENT HOW TO

They have a baseline and a top and bottom edge. It has a baseline, a text box and a top and bottom edge. This is the area in which vertical alignment takes place. LetвЂ™s quickly sum up the most important facts: Now, we know everything to put things into perspective.

(Side note: this text box is called strut in the W3C Specs) Since this text box is tied to the baseline, it moves when the baseline moves. The box is indicated by the green lines in the figures above. Therefore, the text box only just encloses the unformatted text of the line box. Its height is equal to the font-size of its parent element. The text box can simply be thought of as an inline element inside the line box without any alignment. If this character is not aligned in any way, it will sit on the baseline by default.ДЄround its baseline the line box has what we might call its text box. Just add a character at the beginning of the line in questions, like I added an вЂњxвЂќ in the figure. But, you can make it visible very easily. Since the line boxвЂ™s baseline is invisible, it may not immediately be obvious where it is. It means, the baseline is placed where ever it needs to be to fulfil all other conditions like vertical-align and minimizing the line boxвЂ™s height. This is probably the most confusing part, when working with vertical-align. This is the box indicated by the red lines in the figure above.Д¬SS 2.1 does not define the position of the line box's baseline. The line box has a top edge aligned to the top edge of the top-most element of this line and a bottom edge aligned to the bottom edge of the bottom-most element of the line. I also highlighted the area of the text elements by giving them a grey background. This time I drew in the top and bottom of the line boxвЂ™s text box (green, more on this below) and the baseline (blue), too.

In case of no in-flow content the baseline is, again, the bottom edge of the margin-box (example on the right).

So, it is the same as the inline-block elementвЂ™s bottom edge.

In case of in-flow content but an overflow property evaluating to something other than visible, the baseline is the bottom edge of the margin-box (example in the middle).

For this last element its baseline is found according to its own rules.

In case of in-flow content the baseline of the inline-block element is the baseline of the last content element in normal flow (example on the left).

The Inline-block elementвЂ™s baseline depends on whether the element has in-flow content: The Inline-block elementвЂ™s outer edges are the top and bottom edge of its margin-box. The baseline of each inline-block element is shown as a blue line. The boundaries of the margin is indicated by red lines, the border is yellow, the padding green and the content area blue. In the following illustration the top and bottom of line boxes are indicated by red lines.ДЇrom left to right you see: an inline-block element with in-flow content (a вЂњcвЂќ), an inline-block element with in-flow content and overflow: hidden and an inline-block element with no in-flow content (but the content area has a height). Differently sized content means line boxes of different height. All these lines have a so-called line box, which encloses all the content of its line. Once there are more elements than fit into the current line, a new line is created beneath it. Inline-level elements are laid out next to each other in lines. They can have a width and height (possibly defined by its own content) as well as padding, a border and margin. Inline-block elements are what their name suggests: block elements living inline. Inline elements are basically tags wrapping text.

These are elements, whose display property evaluates to

Vertical-align is used to align inline-level elements. Vertical-Align Acts On Inline-Level Elements In a Line Box

For example, it might happen, that the element you changed vertical-align for doesnвЂ™t change its alignment at all, but other elements next to it do! What a joy! Like centering an icon next to a bit of text.Д«ut, it can be a real scumbag sometimes with all its seemingly mysterious rules at work. ItвЂ™s intended use is to align text and elements next to each other. Yep, letвЂ™s talk about the CSS property vertical-align.
