] | You assigned the id to the div tag, but you need to assign the id to the img tag. Then you should get the reference to the image and can then change its src:

<img src ="StarOff.gif" id="1"/>
</div>` | I noticed that `correct_answer` is a Number so I converted it to a String (using `toString`) so it can be used to match the `.image_cell` `id`. I added an `input` to demonstrate it actually functions.

38,884,880 | How can I make a vector of (non-sparse) matrices in Julia? Then I want to use push! to add elements to that.
So if the name of the vector is V, then V[1] will be a matrix or Array{Float64,2}.
I know this works if the elements of the vector are sparse:
V = Array(SparseMatrixCSC). | 2016/08/10 | [

] | You can use the `Matrix` alias (`Array{T, 2}`):
```rb
julia> v = Matrix{Float64}[]
0-element Array{Array{Float64,2},1}
julia> x = rand(2, 2)
2×2 Array{Float64,2}:
0.0877254 0.256971
0.719441 0.653947
julia> push!(v, x)
1-element Array{Array{Float64,2},1}:
[0.0877254 0.256971; 0.719441 0.653947]
julia> v[1]

V = Array(Array{Float64,2}, 0);
edit: As @pkofod suggested, this way is prefered:
T = Array{Float64,2};
V = Array{T}(0)
other options: V = Array{Float64,2}[ ] or V = Matrix{Float64}[ ] |
