Yes of course you can write a text on canvas with ease  and you can set the font name  font size and font color  There are two method to build a text on Canvas  i e  fillText   and strokeText     fillText   method is used to make a text that can only be filled with color  whereas strokeText   is used to make a text that can only be given an outline color  So if we want to build a text that filled with color and have outline color  we must use both of them   here the full example  how to write text on canvas     lt canvas id  Canvas01  width  400  height  200  style  border 2px solid  bbb  margin-left 10px  margin-top 10px   gt  lt  canvas gt    lt script gt    var canvas   document getElementById  Canvas01      var ctx   canvas getContext  2d       ctx fillStyle   red     ctx font    italic bold 35pt Tahoma       syntax    fillText  text   x  y    ctx fillText  StacOverFlow  30 80     lt  script gt    Here the demo for this  and you can try your self for any modification  http   okeschool com examples canvas html5-canvas-text-color

Depends on what you want to do with it I guess  If you just want to write some normal text you can use  fillText

Canvas text support is actually pretty good - you can control font  size  color  horizontal alignment  vertical alignment  and you can also get text metrics to get the text width in pixels  In addition  you can also use canvas transforms to rotate  stretch and even invert text

It is really easy to write text on a canvas  It was not clear if you want someone to enter text in the HTML page and then have that text appear on the canvas  or if you were going to use JavaScript to write the information to the screen   The following code will write some text in different fonts and formats to your canvas  You can modify this as you wish to test other aspects of writing onto a canvas     lt canvas id  YourCanvasNameHere  width  500  height  500  gt Canvas not supported lt  canvas gt    var c   document getElementById  YourCanvasNameHere     var context   c getContext  2d      returns drawing functions to allow the user to draw on the canvas with graphic tools     You can either place the canvas ID tag in the HTML and then reference the name or you can create the canvas in the JavaScript code  I think that for the most part I see the  lt canvas gt  tag in the HTML code and on occasion see it created dynamically in the JavaScript code itself   Code     var canvas   document getElementById  myCanvas      var context   canvas getContext  2d       context font    bold 10pt Calibri     context fillText  Hello World    150  100     context font    italic 40pt Times Roman     context fillStyle    blue     context fillText  Hello World    200  150     context font    60pt Calibri     context lineWidth   4    context strokeStyle    blue     context strokeText  Hello World    70  70
