Consider the following HTML & CSS:

<div><img src='http://makandra.com/images/makandra-ruby-on-rails.png' /></div>

^
img {
background-color: red;
}
div {
border: 1px solid black;
}

This will leave a margin of about 5px between the lower edge of the image and the containing div, although there are no paddings or margins set, and there's no whitespace. The reason is, the image will vertically align baseline, and the space below the image is just kept for descenders (the part of letters below the basel...

Localizing a non-trivial application can be a huge undertaking. This card will give you an overview over the many components that are affected.

When you are asked to give an estimate for the effort involved, go through the list below and check which points are covered by your requirements. Work with a developer who has done a full-app localization before and assign an hour estimate to each of these points.

Static text

• Static strings and template text in app must be translated: Screens, mailer templates, PDF templates, helpe...

You will find this useful when creating responsive designs that work well on small screens.

The attached Javascript gives a container different CSS classes (single_line or multiple_lines) depending on whether its children render on one line or multiple lines.

Initialize it with the selectors for container and children:

$(function() {
  $('.navigation').countLines('a');
});

You can now use different CSS styles like this:

.navigation
  &.single_line a
    // styles when all anchors are rendered on the same line...

Though the W3C even gives it as an example, no browser actually supports this CSS:

img:before {
  content: "something";
}

Browsers will simply not render anything when doing that on images (Fun fact: It worked in an older version of Opera but got dropped).\
The same applies to the :after pseudo-element.

This makes me sad.

You can try using jQuery instead.

It's not logical, so don't be too hard on yourself. You need to give it a height and change the box-sizing and display:

button
input[type="reset"],
input[type="button"],
input[type="submit"],
input[type="file"] > input[type="button"]
  display: inline-block
  box-sizing: border-box
  height: 20px
  line-height: 20px

• Note that you are not allowed to embed any font in a website. You need to check the license first. Fonts from Font Squirrel are all okay to embed and use for commercial purposes, but as with many free fonts, quality differs widely, especially at medium and small font sizes.
• You will need to embed your font in several formats since browser support is a mess.

You can use this code:

function scrollToLine($textarea, lineNumber) {
  var lineHeight = parseInt($textarea.css('line-height'));
  $textarea.scrollTop(lineNumber * lineHeight);      
}

Some caveats about this code:

1. Your textarea needs to have a line-height in Pixels.
2. The code will scroll to the line number in the text area, not the line number of the original text. These will differ if any lines wrap at the edge of the textarea.

The following two hints are taken from Github's Ruby style guide:

If your regular expression mentions a lot of forward slashes, you can use the alternative delimiters %r(...), %r[...] or %r{...} instead of /.../.

 %r(/blog/2011/(.*))
 %r{/blog/2011/(.*)}
 %r[/blog/2011/(.*)]

If your regular expression is growing complex, you can use the /x modifier to ignore whitespace and comments:

regexp = %r{
  start         # some text
  \s            # white space char
  (group)    ...

This is a demo of the "Tabby" Javascript jQuery plugin to use tabs in regular textareas to make them suitable for in-browser coding of languages like HTML, CSS, Javascript, or your favorite server-side language. The idea is to be able to use a press of the TAB button or SHIFT+TAB to indent or outdent your code.

Imagine you have 2 HTML boxes. The first one has a margin-bottom of let's say 30px and the second one a margin-top of 20px. After rules of collapsing margins have been applied we have a margin of 30px (not 50px) between these two boxes . This is because no addition of both margins takes place but the maximum of both is applied. This behavior is called collapsing margins.

Oftentimes it is a good behavior but collapsing margins can be annoying, too. For example child el...

You can change the color for text selection via CSS, using the ::selection and ::-moz-selection pseudo-elements.

Adding this to your Sass will make all text selections use a red background:

::selection
  background-color: #f00

::-moz-selection
  background-color: #f00

Unfortunately, those can't be combined into "::selection, ::-moz-selection". Doing so will have no effect.

This is a very general introduction to MV* Javascript frameworks. This card won't tell you anything new if you are already familiar with the products mentioned in the title.

As web applications move farther into the client, Javascript frameworks have sprung up that operate on a higher level of abstraction than DOM manipulation frameworks like jQuery and Prototype. Such high-level frameworks typically offer support for client-side view rendering, routing, data bindings, etc. This is useful, and when you write a moderately complex Javascript ...

You can now add code blocks without indentation, by using triple-backticks:

You can use text-overflow to truncate a text using CSS but it does not fit fancy requirements.

Here is a hack for the special case where you want to truncate one of two strings in one line that can both vary in length, while fully keeping one of them. See this example screenshot where we never want to show an ellipsis for the distance:

![Flexible overflow with optional ellipsis](https://makandracards.com/makandra/5885-a-flexible-overflow-ellipsis/at...

When using Rails to truncate strings, you may end up with strings that are still too long for their container or are not as long as they could be. You can get a prettier result using stylesheets.

The CSS property text-overflow: ellipsis has been around for quite a long time now but since Firefox did not support it for ages, you did not use it. Since Firefox 7 you can!

Note that this only works for single-line texts. If you want to truncate tests across multiple lines, use a JavaScript solution like...

Twitter's Bootstrap CSS blueprint as a jQuery UI theme. Even if you don't want to use Bootstrap as a CSS framework, this theme looks better than jQuery UI's default theme.

I have no idea how it's supposed to work (or why the don't have a print CSS), but this works for pages written with Markdown:

1. "Edit" the wiki page
2. Copy all text
3. Run a Markdown interpreter and pipe its result, e.g.: kramdown > /tmp/github.html
4. Paste your markdown
5. Press Ctrl-D to finalize your input
6. Open the generated HTML file and print it.

Firefox, Opera and Internet Explorer will repeat elements with position: fixed on every printed page (see attached example).

The internet knows no way to do this in Webkit browsers (Chrome, Safari). These browsers will only render the element on the first printed page.

A pull quote is a typographical technique in which an excerpt or quote from an article is duplicated within the article using a different formatting style so that it jumps out at the reader.

Blatantly copying the excerpt of the pull quote into it’s own element is not the way to go. A pull quote is a purely visual technique, and therefore should not change the structure of the body. Next to that, a structural representation of the excerpt would be seen twice by people using feed readers or services like Instapaper, as well as be re-read for ...
