Disable underline for lowercase characters: g q p j y?

问题

Sometimes you don't want an underline blindly cutting through an underlined page title!
Is there a way to automatically elegantly disable underline for certain lowercasee characters? In these cases it's nicer not to underline these lowercase letters like {g,q,p,j, y}

CSS: h1{ text-decoration: underline; }
PAGE TITLE: George quietely jumped!

A) Is there any way one could achieve such a delicate and advanced styling rule?
B) What other Latin characters do we want to un-underline?
C) How to set the thickness/thinness of the underline?

回答1:

you can as well fake underline with a border-bottom. this can work for single lines and if display properties allows element to shrink on content. (just avoid block ).

here an example with a display:table to allow center text and break line before and after : http://codepen.io/gc-nomade/pen/vJoKB/ What's the idea ?

setting a smaller line-height than font-size, cause the text to overflow from its container.
draw a bottom border to underline text
SVG offers stroke , in CSS , we can do something similar increasing text-shadow with same color as background.
DEMO , you can even set a different color to the simili underline and add a dropping shadow.

In older browser you will lose the box-shadow option, but you still can use the double, groove or ridge border styles with different color than text.

This solution uses jQuery to automaticaly wrap the letters to underline in a <span> tag.

DEMO

As parents with text-decoration:underline "override" children with text-decoration:none; (see here). The technique is to wrap only the targeted letters (the ones to underline) with a <span class="underline"> and apply text-decoration:underline; to that class.

Output :

Signs that will not be underlined :

g  j  p  q  y  Q  @  {  _  (  )  [  |  ]  }  ;  ,  §  µ  ç  /

HTML :

<h1 class="title">George quietely jumped!</h1>

CSS :

.underline {
    text-decoration:underline;
}

jQuery :

$('.title').each(function () {
    var s = '<span class="underline">',
        decoded;
    $(this).prop('innerHTML', function (_, html) {
        s += html.replace(/&amp;/g, '&').replace(/(g|j|p|q|y|Q|@|{|_|\(|\)|\[|\||\]|}|;|,|§|µ|ç|\/)/g, '</span>$1<span class="underline">');
        s += '</span>'
        $(this).html(s);
    });
});

Text Decoration Module Level 3 introduces text-decoration-skip

This property specifies what parts of the element's content any text decoration affecting the element must skip over.

You can achieve the behavior you want by setting it to ink:

Skip over where glyphs are drawn: interrupt the decoration line to let the shape of the text show through where the text decoration would otherwise cross over a glyph. The UA must skip a small distance to either side of the glyph outline.

h1 {
  text-decoration: underline;
  text-decoration-skip: ink;
}

<h1>George quietely jumped!</h1>

Note major browsers don't support it yet.

If you know your background color (assuming white, in this case), give this a shot:

h1 {
    line-height: 0.9em;
    border-bottom: 1px solid black;
    text-shadow: 2px 2px #fff, -2px 2px #fff;
}

the idea:

use border-bottom, and reduce the line-height to pull the bottom of the h1 box model up.
apply two non-blurred, text shadows which will be rendered behind your text, and over your border-bottom. (The first, in this example, is 2px down and to the left; the second is 2px down and to the right.)

fyi - browsers don't play nicely with text-shadow; use it conservatively!

回答5:

It would be a pain in the ass, but I would make an "underline" class and then go in and do it manually

HTML

<h1><span class="underline">Ver</span>g<span class="underline">eten Kanalen</span></h1>

CSS

.underline{text-decoration:underline;}

Here is my solution:

Working Fiddle

CSS:

h1, h2 {
  background-image: linear-gradient(to top, transparent 0px, transparent .15em, red .15em, red calc(.15em + 1px), transparent calc(.15em + 1px), transparent 100%);
  text-shadow: 0px -2px 3px white, 0px -2px 3px white, 0px -2px 3px white, 0px -2px 3px white, 0px -2px 3px white, 0px -2px 3px white;
}

回答7:

Look into text-decoration-skip-ink CSS property. This can specifies how overlines and underlines are drawn when they pass over glyph ascenders and descenders.

h1 {
  text-decoration: black underline;
  text-decoration-skip-ink: auto;
}

<h1>George quietely jumped!</h1>
