did you take that yourself?

naah google haha
kirbyedy
@kirbyedy
@quicksilver774 try to use background-size: cover;
Blake Geraci
@bgeraci714
lol
hm, so is that how you'd use multiple background images as well?
using background-size:cover i mean
quicksilver774
@quicksilver774
i think i tried cover before but ill try again

@sigursiguros
does anyone here know what's the difference between indexOf(a) and indexOf(+a)
somehow one of those worked in my code
and I don't understand the difference
kirbyedy
@kirbyedy
@bgeraci714 background-image: url(top-image.jpg), url(middle-image.jpg), url(bottom-image.jpg);
Blake Geraci
@bgeraci714
i see, so the images will automatically stack themselves?
Thanks a ton @kirbyedy, you've been incredibly helpful

@kirbyedy
here is a nice text about background settings
quicksilver774
@quicksilver774
ill check that article out, thanks!
i tried using the cover method for the size
it chops the bottom portion of my image though

@bgeraci714
can you post more of your code @sigursiguros ?
sigursiguros
@sigursiguros

function pairwise(arr, arg) {
  var index = [];

  for (var a in arr){
    var temp1 = arr[a];

    for (var i = 1; i<arr.length; i++){
      var temp2 = arr[i];

      if (temp1 + temp2 === arg && i > a && index.indexOf(+a) === -1 & index.indexOf(+i) === -1){
        index.push(+a, +i);
        break;
      }
    }
  }

  if (index.length >1){
    var addAll = function (a , b){
      return a + b;
    };
    return index.reduce(addAll);
  }

  else {
    return 0;
  }

}

pairwise([1, 1, 1], 2);
@bgeraci714 it maes a difference when I use indexOf(+a) and indexOf(a) and index.push(+a,+i) vs index.push(a,i)
basically the code wouldn't work without the pluses
which I don't understand why and couldn't find any solution on google
JD Tadlock
@jdtdesigns
@sigursiguros The + just parses the argument. It basically just turns a string value into an integer
sigursiguros
@sigursiguros
i see so indexOf doesn't work on a variable right?
Thanks @jdtdesigns @bgeraci714

@bgeraci714
I just ran your code
and if you print out the values you get from your pairwise function
you get 01 with the +a and +i inside your indexOf
but if you change them to a and i, you get 0112 which is closer to what i think you're looking for
JD Tadlock
@jdtdesigns
@sigursiguros You can pass a variable into indexOf() or use it on a variable(str.indexOf())
Blake Geraci
@bgeraci714
ultimately the answer for pairwise([1,1,1],2) should be 4
@sigursiguros, be careful for that little pitfall. You might actually want the regular a and i as opposed to +a and +i
sigursiguros
@sigursiguros
the pairwise for ([1,1,1],2) should be 1
as the first 1 (index of 0) pairs with the second 2 (index of 1) and sum of 0 and 1 equals 1
sigursiguros
@sigursiguros
so why is passing a and +a giving different results in my code? I don't get it

Hi guys, html question. How do I center an image? <img src="" align="middle"> doesn't seem to work..
Ethan Rose
@ethanrose
would anyone mind taking a look at my weather API project and critiquing it? :D also.. I'm curious as to what the error in the console means, since everything is working as it should be.. thanks!!

sigursiguros
@sigursiguros
@dsonnn align="middle" should work
Ethan Rose
@ethanrose
BY THE WAY---- on my codepen... it can't be https:// so you'll have to change it to http:// :/ I'm pretty sure that's how it has to be for chrome users now.. at least that's how I understand it...
otherwise the https:// codepen won't talk properly to the http:// API ................... that's my understanding
Dickson
@dsonnn
@sigursiguros somehow it works now. Thanks!

@sigursiguros I'm pretty sure that @jdtdesigns has it right but if you do it with the +, you miss out on matches besides the first.

@mutantspore
@aidansven your error is becasue of this in your <head> setup in the codepen settings <link href="css/materialdesignicons.min.css" media="all" rel="stylesheet" type="text/css" />
