                h1 Photoshop images with CSS blend-modes

.content__intro
  h2 Intro
  .description
    p Before I learned how to write "the codez" I was a photographer. In photoshop, there are 3 simple techniques to lighten, darken and colorize  images quickly. Now we can do these same techniques with CSS. 
  
.content__lighten
  h2  Lighten a dark image
  .description 
    h3 (under exposure)
    p Sometimes you get a dark image and you wish you could lighten it. Well you can—using the same quick method you'd use in photoshop. Just duplicate the layer and set it's blend mode to screen.
  
  .media-1
  
  .description 
    p Below I took the exact same image and gave it multiple backgrounds of itself. I know, this sounds weird, but you can totally create multiple background images in CSS.
    
    pre
      code background-image: url(photo-1.jpg), url(photo-2.jpg)
    
    p We can then lighten that image by adding: 
    
    pre
      code background-blend-mode: screen
      
    p In this case, I did three layers of the same image to make the effect stronger. You can add as many layers as you'd like.

  h2  Darken a light image
  .description 
    h3 (over exposure)
    p Sometimes you get a light image and you wish that you could darken it. We can do that using the inverse of the method above.
  
  .media-1
  
  .description 
    p Again, we use the multiple background trick to make 2 layers of the same image. Then we set:
    
    pre
      code background-blend-mode: multiply
      
    p Boom! Done. Darkening accomplished.

  h2  Colorizing 1
  .description 
    p Sometimes you just want to make an image look cool. Maybe you want to colorize an image to set text over it. Regardless, colorizing is easy. 
  
  .media-1
  
  .description 
    p This time we use one image and a background color:
    
    pre
      code
      | background-image: url(image.jpg)
      | background-color: #0fc
      | background-blend-mode: multiply
  
  .media-2
  
  .description 
    p Below we use a "screen" blend mode:
    pre
      code
      | background-image: url(image.jpg)
      | background-color: tomato
      | background-blend-mode: screen
  
  .media-3
  
  .description 
    p Bleow we use an image with a "linear-gradient" background as a second image
    
    pre
      code
      | background-image:  url(image/jpg), linear-gradient(135deg, red, blue)
      | background-blend-mode: overlay
  
  .media-4
  
  .description 
    p Bleow is another, but using "hard-light" instead.
  
  pre
      code
      | background-image: url(image.jpg), linear-gradient(45deg, red, green, blue)
      | background-position: center center
      | background-blend-mode: hard-light

  h2  Colorizing 2
  .description 
    h3 (Black and White)
    p You can also turn a color image to a black-and-white image too, but the technique is a little different.
  
  .media-1
  
  .description 
    p This time we use a pseudo-element to place a background color over the image.
    
    pre
      code 
        | &::after
        |   content: ''
        |   position: absolute
        |   top: 0
        |   left: 0
        |   background-color: #ccc
        |   width: 100%
        |   height: 100%
        |   mix-blend-mode: color
      
    p You can use this technique to create any monotone image.

  .description 
    p I could do this forever. There are so many options. I'd argue that the most usable blend-modes are multiply, screen, overlay, soft-light, hard-light and color.
    
    p If you use a background-image and background-color on the same element, the image will alway sit on top. The blend mode is applied top down. Thus, the image ends, up with the blend-mode. 
    
    p To make some blend modes work, you need to place the background-color over the background-image. This requires using an absolutely positioned pseudo-element to sit on top of the image. We will also need to use "mix-blend-mode" instead of "background-blend-mode."
    
    h3 Important note!
    p While most of the exmaples in this pen used background images with blend-modes, you can use the technique in Colorize 2 to apply blend-modes to img tags. Just put a pseudo-element over the img and use "mix-blend-mode."

    p Don't be intimidated by Jade and Stylus. Just click the new "View Compiled" buttons in the code window to get the compiled source codez! You can then convert them into whatever you want (css to LESS or css to scss)
