How to keep video full size while minimizing? - html

I am trying to set full screen autoplay background video. Here is the link where I got the video, https://pixabay.com/en/videos/saigon-landscape-vietnam-travel-14385/
It looks quite well on fullscreen however when I minimize the screen there comes the white space at the top? How can I avoid it? I wrote a media query in css
#media only screen and (max-width: 900px) {
video {
background-attachment:unset;
position:absolute;
margin-top: -500px !important;
}
}
I guess it is not a good idea to set margin top.
Here is my html and css code
body {
font-family: 'Poppins', sans-serif !important;
}
.w3-bar-item {
margin: 0;
padding: 40px 10px 5px 10px !important;
color: whitesmoke !important;
font-weight: 700;
}
.showcase h1 {
color: floralwhite;
font-family: 'Poppins', sans-serif !important;
margin: 0 auto;
margin-top: 300px;
font-size: 3rem;
font-weight: 500;
text-transform: uppercase;
}
.showcase p {
margin-top: 30px !important;
font-size: 1.2em;
color: whitesmoke;
max-width: 900px;
margin: 0 auto;
}
.showcase button:hover {
background: darkred !important;
opacity: 0.8 !important;
color: white !important;
}
.showcase {
margin-bottom: 50px !important;
}
#media only screen and (max-width: 900px) {
.showcase {
margin-bottom: 5px !important;
}
.showcase h1 {
margin-top: 200px;
}
}
.section {
padding: 10px;
}
.section img {
width: 100%;
}
.w3-tag {
margin: 6px 0 0 6px;
}
video {
background-attachment: fixed;
position: fixed;
background-size: cover;
top: 60%;
left: 50%;
margin-top: -50%;
margin-left: -50%;
z-index: -1;
max-height: 1000px;
opacity: 0.9;
}
button {
margin-top: 5px !important;
border-radius: 10px;
}
footer {
background-color: darkslategray;
color: white;
}
footer p {
margin: auto;
padding: 10px 0px 5 px 0px;
font-size: 1.2em;
font-weight: 500;
}

Why not simply doing it like this:
video {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
min-height: 100%;
min-width: 100%;
}
Your background rules do not apply to video.

I did set the Z-index for the showcase content to be in front of the image, but it doesn't work. I have tried an identical approach elsewhere and that works.
Am I doing something incorrectly?
Please help, Thanks!

max-width is not working in css to change size of image dynamically?

The problem is max-width(tm-section img ) is not scaling according to the browser. And before that I wanna ensure that it is not my browser problem as I had checked working of same with different code and its working.
the image is not changing according to the browser.

If your container is tm-section then you can use the following and it will resize to its container:
tm-section img {
position: absolute;
left: 0;
top: 0;
width: 100%;
height: auto;
}
%: Defines the maximum width in percent of the containing block.
You should set width for .tm-section
EX:
.tm-section {
width: 800px;
}
.tm-section img {
max-width: 100%;
}

In your code add the absolute positioning for container to overlay the content. Second thing add the transparent background color :before for top-wrapper class. And also I adjusted the padding based on header height.
body {
margin: 0;
font-family: "Hiragino Kaku Gothic ProN";
}
* {
box-sizing: border-box;
}
a {
text-decoration: none;
}
.mt-50 {
margin-top: 50px;
}
.container {
max-width: 1170px;
width: 110%;
padding: 0 15px;
margin: 0 auto;
position: absolute;
left: 50%;
top: 50%;

html5 picture tag does not work on mobile devices

I have been programming quite a long grid system, where I used the html5 <picture> tag. When a device is < 650px there should load picture 1, and > 650 picture 2. I was testing this with minimize chrome browser.
The fallback picture is a test picture.
I now test this on an iPhone, and I can see the fallback picture is loaded everytime. So now I panic because I used 3 days for making this grid, and it looks like the main purpose of making the grid is not working.
See the demosite here.
Does anybody have a clue of why it is not working?
(I cut away a lot of code, there is not relevant for the question. But I posted all the CSS that I am using)
.
