One common criticism of this website is that there’s too much “wasted space.” Web developers have a tendency to cram as much information on your screen as possible. Robert Bringhurst - The elements of typographic style Typographically, poise is made of whitespace. Using white space onlineīig type, even huge type, can be beautiful and useful.But poise is usually far more important than size – and poise consists primarily of emptiness. It’s as simple as that, yet it’s often white space that separates good design from bad-almost always because there isn’t enough of it. Generally speaking, white space is any empty area of a design or composition the margins in a book, or the sky in a painting: The most common whitespace character, is the word space The one you get when you press the space bar. Whitespace characters denote the empty space between all the characters you can actually see.They have width (height if you’re writing vertically), some special rules, and not much else. _fillText = Ĭ copy and paste Unicode whitespace characters - and learn how and when to use them. Offset += + javascript would be var _fillText, X + offset + args # in case any additional args get sent to fillText at any time Return _fillText.apply this, arguments unless we need to remember some stuff as we loop
#Letterspace vs hairspace code
The supporting code is: _fillText = CanvasRenderingContext2D::fillTextĬanvasRenderingContext2D::fillText = (str, x, y, args.) -> Here's some coffeescript that allows you to set kerning to your context like so tctx = tcanv.getContext('2d') In the meantime I will put this here for others to see if they are looking for a solution on this. Still hoping that someone will point out any flaws in the process. I'm also not sure how good Verdana's default kerning is, though I understand it's better than Arial - suggestions on other fonts to try gratefully accepted. Ideally I'd throw multiple random strings at it and do a pixel by pixel comparison. This.fillTextWithSpacing(textContext1, text, 0, 0, 0) TextContext1.font = "72px Verdana, sans-serif" TextContext1 = element1.getContext('2d') Subtract the width of the shorter string from the width of the entire string, giving the kerned width of the character, wChar = wAll - wShorterĬode for demo/eyeball test: element1 = document.getElementById("Test1")
Measure wShorter, the width of the resulting shorter string using measureText(). Print the first character at position (X, Y) using fillText()
Remove the first character from the string Measure wAll, the width of the entire string using measureText() Here's the code: this.fillTextWithSpacing = function(context, text, x, y, spacing) Here's the HTML: Your browser does not support canvas. If you have any comments on it then I would point you to my question on the subject ( Adding Letter Spacing in HTML Canvas)īasically it uses measureText() to get the width of the whole string, and then removes the first character of the string and measures the width of the remaining string, and uses the difference to calculate the correct positioning - thus taking into account kerning pairs and the like. It should take that into account, and rough testing suggests it does. To allow for 'letter kerning pairs' and the like, I've written the following. Note also that 'rolling your own'-drawing each character with a custom offset-is going to produce bad results for most fonts, given that there are letter kerning pairs and pixel-aligned font hinting. Use HTML layered with Canvas and perhaps even SVG, each doing what it does best. I would suggest that you should combine the appropriate technologies for each usage. This is not possible the HTML5 Canvas does not have all the text-transformation power of CSS in HTML. Var inp = document.querySelectorAll('input'),
