background-blur | Ultra light cross browser image blurring plugin for jQuery | Plugin library

I have this code.

1. The problem is that as you can see, I get those blue lines in the links area and I tend to think it's from the padding used for read-more and I can't understand why they appear and how to remove them.

I also have another misunderstanding. 2. Why does the green border (.middle) have that size? No size is set in the code.Its parent is background-blur, but its size is set in the code for the whole screen.

1. If a child is sized with vw, its size depends on the size of the entire viewport, or the father's viewport, because I played with these units and not always an element with 50vw is equal to another element with 50vw.

In this snippet, I used vw and sometimes 5vw seems very much and sometimes very little and I don't understand why.

I have this code. When inspecting from the browser ,it seems when i click on hamburger-menu active class doesn't work. I expect when I press the hamburger menu the container class to become the container.active class Also,I set cursor: pointer for hamburger-menu and for link a(read-more) and it doesn't work. Any help?

I am using this code to create a background-blurred view:

I'm trying to implement a background-blur effect with OpenGL.

Here is my thought:

1. drawing all background element to colorFBO
2. draw colorFBO into pingpongFBO[0] and pingpongFBO1
3. use pingpongFBO[0] as texture, draw hori-blur rect to pingpongFBO1
4. use pingpongFBO1 as texture, draw vert-blur rect to pingpongFBO[0]

Here is the result with blur radius of 200:

Result

As you can see, the hori-blur effect disappeared almost.

The edge of blue rectangle is still sharp.

If I only draw hori-blur part, it looks correct, the edge is now blurry.

Hori Only

Here is my blur frag shader code

I want to change 'background-image' when i access the page.
