Razor Pages ASP.NET Core 6 - How to add background image with blur - html

I have successfully added a "background-image" to my Razor Pages application.
Now, when using "filter: blur(2px);" the header and footer blur, but not the image.
I've been at this for hours, saw tons of threads on how to add the image, but couldn't find a way to do this properly (the blur), or see someone else experiencing the same behavior.
My _Layout:

</html>
My CSS - using site.css to apply changes globally - is:
html {
font-size: 14px;
width: 100%;
height: 100%;
}
#media (min-width: 768px) {
html {
font-size: 16px;
}
}
html {
position: relative;
min-height: 100%;
}
body {
margin-bottom: 60px;
background: url(../img/background.jpg) no-repeat center center fixed;
background-size: cover;
width: 100%;
height: 100%;
color: white;
}
So far so good.
Now when adding to my css:
body {
margin-bottom: 60px;
background: url(../img/background.jpg) no-repeat center center fixed;
background-size: cover;
width: 100%;
height: 100%;
color: white;
filter: blur(2px);
}
The footer and header blurs, but not the background-image as anticipated.

Replace filter: blur(2px); with backdrop-filter: blur(2px);.

filter will affect the element itself, and backdrop-filter will affect the elements beneath the element within the bounding box of the element.So in your project, you need to use backdrop-filter. You can follow this link to learn more about backdrop-filter.

Bootstrap theme not as wide as parent container

I need help with bootstrap container and row width.
I have created a container and a row inside it. I have everything inside the row, but for some reason content sizes are different as displayed on jsfiddle and image preview.

Image preview
On the image you can clearly see, where the spaces are. It all should be aligned from side to side inside the container. Logo column width is missing a few pixels on the right and the two boxes in the bottom are not touching the sides of parrent container.
The problem is from this div.
<div class="col-md-8">
as well as <div class="col-md-4">
Yes they both equal 12 but they contain a margin.
To fix this you can add a class like this.
.nomargin{
margin: 0px !important;
}
And use the class like this
This will remove the default bootstrap margin.

Bootstrap; formatting a row/section background properly

I am trying to get the background of my block section to encapsulate the image, or be responsive to what is put inside. Honestly, I don't even know what I am trying to ask, I just want the white space to respond to the image size, so I can have a background color/image behind a set block section for my About me. I have tried messing with padding/margin but I cannot seem to get it done correctly. In case the image doesn't load, I have my .html and .css code below
Code

min-height: 100%;

}

margin-bottom: 30px;

Hey guys,
if you view my site on your browser you will see that as you scroll down the 'h1' which says "My skills" is located just before the start of the next page.
https://codepen.io/JamesMcGill/pen/KGNEWd On codepen it's even worse.
I am having a difficult time trying to figure out why this is happening.
Well, technically it is not on the same page. However, it does appear within the same background image as the contents on the main welcoming page.
Please, give me some suggestions on how I might be able to address this issue.
Thank you..
You applied the background-image to the body element, which will cause it to fill the screen. If you want it to only cover the first section, you should apply the background-image rule to that specific section.
It is doubling up at the bottom because background-repeat: repeat is the default and you have not declared an alternative. If you want if to fill the screen, you can add background-size: cover, or simply add background-repeat: no-repeat to prevent the doubling.

how to make background image transparent and the text written on it should be highlighted

Since I am not able to make the background transparent, means I want the image opacity should be minimum and the text written on it should be highlighted. Please help me out from this. As I used css opacity but the whole div is getting transparent with the text also written on it.
Here is my html and css:

I think this is what you need. We can achieve background transparent by using pseudo class. Please check the below code.
.bgimg{
width: 100%;
height: 600px;
}
.bgimg::after {
content: "";
background: url('https://images.pexels.com/photos/137219/pexels-photo-137219.jpeg?auto=compress&cs=tinysrgb&h=350');
background-size: cover;
background-position: center;
background-attachment: fixed;
opacity: 0.3;
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
}
.headerset{
padding-top: 250px;
box-sizing: border-box;
}
.headerset h2{

Padding-top won't work

I am trying to put my "Sanchez Designs......Ms Sanchez....and "Web Developer, Artist and Higher Education" buttons midway into the page, right about at the peak of the mountain. I have researched and tried but am unable to move it. I thought padding-top would do the trick but nope. Any suggestions?
Also, I'm learning web development so please be gentle. Thanks!
