Arctext.js – Curving Text with CSS3 and jQuery

While CSS3 allows us to rotate letters, it is quite complicated to arrange each letter along a curved path. Arctext.js is a jQuery plugin that let’s you do exactly that. Based on Lettering.js, it calculates the right rotation of each letter and distributes the letters equally across the imaginary arc of the given radius.

While CSS3 allows us to rotate letters, it is quite complicated to arrange each letter along a curved path. Arctext.js is a jQuery plugin that let’s you do exactly that. Based on Lettering.js, it calculates the right rotation of each letter and distributes the letters equally across the imaginary arc of the given radius.

How it works

The main idea behind the Arctext plugin is to rotate letters with CSS3 transforms in order to place them along a curved path. The curve is always a segment of a circle (hence arc) for which the radius can be specified. The space and rotation for each letter will be calculated using that radius and the width of the text.

Options

The following options are available:

radius	: 0, 	
// the minimum value allowed is 
// half of the word length. 
// if set to -1, the word will be straight.

dir		: 1,	
// 1: curve is down, 
// -1: curve is up

rotate	: true,	
// if true each letter should be rotated.

fitText	: false 
// if you want to try out the 
// fitText plugin (http://fittextjs.com/) 
// set this to true. 
// Don't forget, the wrapper should be fluid.

  1. Not sure what other are saying about not working in IE – seems to work fine on my versions. A question: how do i get rid of using webfonts and just use whatever i specify in my CSS? I thought getting rid of the following – or part thereof – would fix it but to no avail.

    I have stripped the code back to example 1:

    var $example1 = $('#example1').show(); google.load('webfont','1'); google.setOnLoadCallback(function() { WebFont.load({ google : { families : ['Montserrat','Concert One'] }, fontactive : function(fontFamily, fontDescription) { init(); }, fontinactive : function(fontFamily, fontDescription) { init(); } }); }); function init() { $example1.show().arctext({radius: 500}); };

    Which works well. i thought if i got rid of – or part thereof – the following code it would still work:

    google.setOnLoadCallback(function() { WebFont.load({ google : { families : ['Montserrat','Concert One'] }, fontactive : function(fontFamily, fontDescription) { init(); }, fontinactive : function(fontFamily, fontDescription) { init(); } }); });

    Any ideas?

  2. I dunno how do you guys at Codrops come up with these innovative ideas. Some of the best tutorials I’ve ever come across are on this blog. Keep it up !

  3. nice!!!, cool for us retarded people that cant really use ‘them there fancy picture book learnin photoshop tricks’
    funny thing was is that i was struggle with this very same thing this morning assigning damn text to vector paths……d’oh!

    the first tweak i can see is to assign a rotation given some data or a trigger event.
    interesting set of adjustments would be to replicate a watch purely without images and a ‘snap into place’ day/date dial or window.

    the UI possibilities for just this example are endless.

    thanks for a great bookmark

  4. The first animation option in chrome and windows OS makes the text “blink” and moves it offset

    • I agree with the “blink” part. I am sure if you set the backface-visibility to hidden (spans) it will not blink. Cheers

  5. I was actually looking to do something like this not too long ago. Great, but a bit late πŸ™

  6. Hi Pedro

    Great tutorial, I recently experimented with slanted text using css3, but this plugin opens up a range of possibility’s. It would be great to use something like this when creating logo’s to include company names and slogans as real text. It is a shame there is no workaround for internet explorer but this is still something I will look to use in the future.

  7. I went looking for the Github link and finally realized there wasn’t one. Felt weird, like I was living in the past (4 or 5 years ago) πŸ™‚

  8. Pedro, really nice work! It looks great.

    I’ve been trying to modify it so it can support rendering on the Y axis instead of the X axis. Sadly I’m not that great at math and haven’t been able to get it working right. Any chance you could help out? What part of the math needs to change to support rendering on the Y axis (basically rotate everything 90 degrees or -90 degrees)?

  9. This looks fantastic. Can someone give instructions on how to implement this? I don’t have any knowledge of js.

  10. If I dynamically update the content, the plugin does not work. (Code below)
    Anyone knows how to fix this?

    $example1.html(“Something else”);
    $example1.arctext({radius: 500, rotate: true});

    • Eventually I remove the element from the dom and insert a new one before calling arctext again. It works… in a very ugly way.
      Still looking for an elegant solution. Thanks.

  11. I just wonder how can use the same concept to put instead of text, a series of images and then transform over the curve, any idea?

  12. can anyone tell me where is the file Lettering.js in the source code??i cant find it and the text is not being rotated.

  13. Really great tut thanks

    I was looking for something like this about 4 months ago!!

  14. Great plugin, befor i’ll try to use it, i’d like to know about the accessibility of SEO (every letter in a span) ?
