Styling a numerical value to appear as currency with CSS

Question

Styling a numerical value to appear as currency with CSS

Is there a way to style the content of an element as currency using just CSS? It would be great to know if we can control how the value is displayed with CSS. I haven't found anything yet, so not getting my hopes up :)

<!DOCTYPE html>
<html>
<head>
    <style type="text/css">
        .dollars:before { content:'$'; }
    </style>
</head>
<body>
    Using only CSS: <span class="dollars">25153.3</span>
    <br />
    Desired format: <span>$25,153.30</span>
</body>
</html>

The output of that example will be:

Using only CSS: $25153.3

Desired format: $25,153.30

I am aware that it's quite simple to achieve this using javascript - http://css-tricks.com/snippets/javascript/format-currency/.

Answer №1

To format currency in a web page, CSS and a touch of Javascript are necessary for adding commas to the numbers. By using a CSS class, additional styling such as displaying negative values in red or adding a currency sign (e.g. $ Dollar sign) can be achieved. The steps to accomplish this are:

1) Convert the value to a number and add commas based on locale

Number(value).toLocaleString('en');

2) Apply a class to distinguish between negative and positive values (e.g. set text color to red)

.enMoney::before {
    content:"$";
}
.negMoney {
    color: red;
}

var amount = 25153.3;
console.log(amount.toLocaleString());

/------

var amount = 25153.3;
result="$ " + amount.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2})
console.log(result);

console.log();
//---------------------------------------------------

// format as currency in USD
console.log(amount.toLocaleString('us-US', { style: 'currency', currency: 'USD' }));
// → $ 25,152.30 

// format as currency in EUR
console.log(amount.toLocaleString('de-DE', { style: 'currency', currency: 'EUR' }));
// → 25,152.30 €

// Japanese yen format without decimal places
console.log(amount.toLocaleString('ja-JP', { style: 'currency', currency: 'JPY' }))
// → ￥251,53

If you're wondering about the limitations of CSS when it comes to number formatting (such as parsing a number from a string and adding separators), CSS just isn't equipped for that task. It's not what CSS was intended for.

If you need to format numbers, a better option would be to use XSLT. Here's an example:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="span[@class='dollars']">
        <span>
            <xsl:text>$</xsl:text>
            <xsl:value-of select="format-number(current(), '###,###.00')"/>
        </span>
    </xsl:template>

    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

Unfortunately, this method may not fit your specific use case, but it could be applied to integer numbers ranging from -999 to 999.

.currency:before{ content:'$'; }
.currency:after{ content: '.00'; }

<span class="currency">789</span>

If you're working server side, one possible albeit tedious solution is to convert the number to a reversed string and iterate over each character. You could then style the characters within li elements using CSS for formatting. However, this approach seems unnecessary as you could simply author the string directly.

.currency li:before{ content: ' ,';}
.currency li:first-child:before{ content:'$' !important; }
.currency *{ display: inline-block; }
.currency, .currency > *{ display: inline-block; }
.currency:after{ content: '.00'; }

<ul class="currency"><li>123</li><li>456</li><li>789</li></ul> 
<ul class="currency"><li>456</li><li>789</li></ul> 
<ul class="currency"><li>789</li></ul>

For a more complex yet ultimately futile effort, you could add a

<style> .currency:after{ content: '.00'; } </style>

above the <ul>, allowing CSS to modify the decimal value, which would be quite amusing.

Alternatively, if you opt to utilize JavaScript, the CSS technique might prove somewhat practical. You can input an integer or double (of any precision) and have JS separate it into <li> elements.
