background image + triangle shapes in CSS
# November 30, 2012 at 7:47 am
Hi everybody !
I was able to generate the shape I want using css (using borders), but I’d know like to map a background on it. I tried a few solutions but I didn’t found anything working in CSS.
You’ll find an example there: http://codepen.io/jmorel/full/rIDAe
Is there any way (other than using images for the shapes) that I can extend the stripes background to my .top and .bottom divs while preserving the shape ?
I sure hope there is, I’m rubbish with Photoshop.# May 10, 2013 at 10:28 am
Basically the trick to making a CSS based triangle use the border-image property and actually get the expected appearance seems to lay largely in the image used.
The CSS I used last time I did this goes something like this.
border: 150px outset transparent;
border-top:0px outset transparent;
border-left:150px outset transparent;
border-right:150px outset transparent;
border-image: url(“pyramid_border_image.png”) 150 150 150 150 stretch stretch;
height :1px; width:1px;
padding :0; margin:-1px;
I’m sure that could be thinned out some , but at the time I just wanted to see if I could do it, however I might be revisiting it soon as I want a pyramid for one of my css3 3d things.
As I was mentioning , the trick seems at least to me to be mostly in the image , specifically the corner pieces for the lower left and lower right corners in the border image. These corners themselves need to have their squares contain 1/2 transparent and 1/2 pattern at the appropriate 45 degree angles for the two bottom corners of the triangle.
With the properly made image , it’s fairly straight forward after that.
