Incorporating the <sub> element while maintaining the line height

Question

Incorporating the <sub> element while maintaining the line height

I am facing a challenge with formatting text that includes subscripts and superscripts tags. For example:

<div>hello <sub>world</sub>, how are you? Translated as logical aggregates or associative compounds, these characters have been interpreted as combining two or more pictographic or ideographic characters to suggest a third meaning.</div>

To see this issue in action, visit http://jsfiddle.net/BzqFb/

I have noticed that lines of text with subscripted content are wider than those without it. Is there a way to change the CSS style for the tag to ensure that all text lines have the exact same height?

Are there specific types of texts that can cause a line's height to change within an HTML document?

EDIT: I am specifically looking for subscript behavior, not just smaller text. Even increasing the line-height does not fully address the width difference between lines with and without subscripted text.

Is there a way to change the style of tags in CSS and ensure that all lines of text have the same height?

Instead of trying to adjust line heights, you could simply use the <small> element to keep the text vertically aligned:

<div class="container">hello <small>world</small>, how are you? ...</div>

Check out the Demo on Fiddle

In response to the Original Poster's comment, you can utilize position: relative; for the subscript element and adjust the top property to maintain consistent line heights throughout the text:

sub {
    vertical-align: text-bottom; /* <-- Reset user agent stylesheet   */
    position: relative;          /* <-- Set element position       */
    top: .2em;                   /* <-- Adjust vertical positioning */
}

Avoid using the sub element altogether. Instead, consider using something like

<span class=sub>...</span>

along with a style sheet to lower the content vertically and adjust the font size if needed. To achieve vertical lowering, you can apply position: relative with an appropriate value for top or bottom; this will displace the content without impacting line spacing. For instance,

.sub { position: relative; top: 0.8ex; font-size: 75%; }

Alternatively, you could use the sub element and neutralize its impact on vertical placement by using vertical-align: baseline. However, this may cause issues in setting the font size consistently across different browsers due to a significant bug in IE (where it interprets a percentage in the font-size property of sub relative to the default size of the element instead of the parent element's font size as other browsers do).

Note: While the sub element does not affect the line-height, it often increases the height of line boxes, making it impossible to resolve the issue solely by adjusting the line-height.

Here's a neat little trick you can try

def {
    text-align: center;
}

It works like charm, giving your text that extra oomph. http://jsfiddle.net/BzqFb/8/

You could also opt for a span and tweak the font size to achieve a similar effect

Check out the line-height CSS property in action using this JSFiddle example:

.container {
    width: 300px;
    line-height: 30px;
}

When using the subscript tag, remember that it makes the text appear smaller and below the current line. If you want to adjust the positioning, you may need to override the default property with vertical-align: sub;, or avoid using the subscript tag altogether.

Edit made after revising the question:

Contrary to popular belief, a subscripted line is not wider than any other line. It may appear so because the next word in the line exceeds the available width, causing it to wrap to a new line. You can validate this by checking out this JsFiddle demo. Another option is to use text-align: justify to make all lines justified. Take a look at this third JsFiddle example for more clarity.
