Html not loading - css

Im quite new to html and i bet i'm missing something but im creating a simple html and css to go along with it. i get 404 whenever i preview my work.
this is the html code:
<!DOCTYPE html>
<head>
<meta charset="utf-8">
<title>Basic Structure</title>
<!-- !CSS -->
<link rel="stylesheet" href="/fbtab/fbtab.css">
</head>
<body>
<div id="container">
<header>
<div id="logo"><img src="/fbtab/images/logo.png"/></div>
</header><!-- end header -->
</div><!-- end container -->
<!-- !Javascript - at the bottom for fast page loading -->
</body>
</html>
And this is the css:
html,
container,
header,
body {
width:800px;
height:100%;
min-height:100%;
}
Can someone guide me to the proper way of creating new html page?
i just need a 800px width page and want to put logo and icons for it and a background.
Thank you.

That does not have to do anything with your HTML. A 404 error means that a page does not exist. Maybe the file upload (of your HTML) has failed. Your server cannot find the file you have requested. Check via FTP if your files have been properly uploaded.

A 404 error is an HTTP status code that means that the page you were trying to reach on a website couldn't be found on their server. (and has no relation with page layout and design)
Technically, an Error 404 is a client-side error, implying that the error is your mistake, either because you typed the URL in wrong or the page has been moved or removed from the website and you should have known.
But in your case, if you are calling the domain (like google.com) and not a specific page (like google.com/index.html);
Make sure that you have given the name index.html to your web page
Make sure that you have uploaded / created / copied your index.html file in the server root directory (htdocs folder).

Try to add <html> tag before <head>.

Image link generated using Firebase Dynamic Links not working in browser

I am using Firebase Dynamic Links REST API to generate short links.
If I paste that link into the browser it redirects and loads the appropriate image. But when I use the same link to load image in <img> tag in my webpage it fails.
I created a sample(codesandbox link below) trying to load the same image. I put two image tags, one with bit.ly shortener and one generated with the firebase dynamic links generator. The bit.ly link loads fine.
Sample codesandbox : https://codesandbox.io/s/using-img-tag-forked-ufnd31?file=/index.html
Sample short link for a image : https://files.flux.chat/vs4fy3cY7s1aMnS57

HTML code
<!DOCTYPE html>
<html>
<head>
<title>Parcel Sandbox</title>
<meta charset="UTF-8" />
</head>
<body>
<div>
<img class="image" src="https://files.flux.chat/vs4fy3cY7s1aMnS57" />
<img class="image" src="https://bitly/3Lr8Bq1" />
</div>
</body>
</html>
I don't have any experience with this, but I think shortened urls won't work as an image source-- they don't point to an image directly, they redirect to an image.
Here's an old answer that seems relevant: https://stackoverflow.com/a/27062627/954986
That is not possible unless you own the domain where you want the shortened URL. For example, to do that, you would need to own (or have access to) the website bit.ly.
bit.ly is not hosting your video or your image, it only redirects them to the real URL when you click on the link.
[...]
You will see that your image is NOT in the code. It only redirects to the page that DOES contain your image.
Perhaps you could make an XHR request in javascript, and see if it returns a 3** status with some other location, and use that as the source for the image? (edit: the short link doesn't have CORS enabled, so this probably won't work)
I just tested with curl (well, httpie which is far superior), and the sample shortlink you provided gives a 302, with the Location response header being the actual image.
edit: I tested your sandbox, and the flux.chat image source shows a GET request resulting in a 403 Forbidden status code in the browser console. Maybe it's because it's being called from localhost? But firebase sees something about the request it doesn't like (maybe origin being localhost, maybe it being in an image source, maybe ..?) and that's preventing it from loading.
Sorry I don't have anything more concrete for you, definitely a strange issue.

OG tags not working with react-helmet and Netlify

I cannot for the life of me figure this out. The following site is hosted on Netlify and prerendering is enabled. When inspecting the page, all of the OG tags are correct. These tags are injected using react-helmet.
https://browniepoints.africa/opportunities/volunteer-at-a-soup-kitchen-every-week-on-thursdays
When scraping the above URL on the Facebook debugger, it responds with:
The following required properties are missing: og:url, og:type, og:title, og:image, og:description, fb:app_id
The only one of those errors/warnings that should be there is the app_id, which I don't care about.
I've waited well over 48 hours for caches to clear, I've tried scraping with query strings appended to the URL, and the images have absolute URLs. But not even the description tag is pulling through.
Can somebody that uses react-helmet and Netlify please shed some definitive light onto this problem?
This is related to a known prerendering issue.
My fix was to remove the <!DOCTYPE html> declaration from the index.html file as a temporary workaround until the above issue is resolved.
While I can't tell you exactly why. your SSR is not working correctly. Go to Chrome DevTools and click the 3 vertical dots next to Console:
Select Networking Conditions, then uncheck Select Automatically and enter Googlebot/2.1 (+http://www.google.com/bot.html):
Now refresh the page and notice that all you see on the site is some plaintext saying "html" and even your javascript bundle is missing. This is what your html looks like:
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="fragment" content="!">
<link rel="shortcut icon" href="/favicon.ico">
<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no">
<title>Brownie Points</title>
<link href="/static/css/2.3bf0f3c5.chunk.css" rel="stylesheet">
</head>
<body><noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
</body>
</html>
Note that Netlify SSR is in Beta but I personally didn't have those issues with it. Have you done any other steps other than enable it? I have tested it to be working with a CRA generated app before.

css is not working in my web2py application

I am building a web2py application.
I use my own css file called style.css
I do know that the following code
{{response.files.append(URL('static','css/base.css'))}}
{{include 'web2py_ajax.html'}}
will link my css file to my application.
I use this for layout.html; which is used for every page of application.
Initially, I do not have problem with this...
Suddenly, at some point, my css is not updated...
Every css before the point, works fine.
Every css after the point, do not work at all.
In web2py editor, all css changes are updated. However, If if run it, the css is not updated... If I inspect the css code using chrome, the css is not updated and remain to previous css file..
for clarification, I give you example
initially I just have the following.
#title{
font-size: 90px;
}
then I change it to the following
#title{
font-size:100px;
}
IN the web2py editor, the change is saved and set it to 100px. However, if i run the application and view css file using chrome inspect, it is still remained as 90px.
I thought the server may have some error, so I restarted. I still get error.
Another thing I can think of is the confit with bootstrap..
The following is the head part of layout.html
<head>
<title>NR</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
{{response.files.append(URL('static','css/bootstrap.min.css'))}}
{{response.files.append(URL('static','css/style.css'))}}
{{include 'web2py_ajax.html'}}
</head>
Actually, I do have a solution...
If I create css file with different name, and copy and paste all css work, it work!!
However, this takes extra work... create new css file and copy and paste.... It is not good way.
Can you help me?
Thank you
Perhaps your web server is configured to set the HTTP response headers so the assets will be cached by the browser (in which case, they will not be re-sent on every request). If this is just a development issue, you can simply force your browser to reload all assets (e.g., by pressing CTRL-F5).
For a more general solution, see the documentation on static asset management.
Another option is to let web2py serve the static content itself, in which case, the assets will be re-requested with each page and web2py will return 304 responses if the assets have not changed since last sent.

Play swf file on webpage

Hey guys I am trying to play a .swf file on my web page I have already tried to embed it using HTML and it works. But is there anyway of playing a .swf file after button click event in asp.net?
Before you get to carried away with using flash could I urge you to read this http://occupyflash.org/ and then invest a little of your time researching html5 (specifically canvas) :)... http://www.williammalone.com/articles/flash-vs-html5-canvas-drawing/ and this http://webdesign.about.com/od/html5tutorials/a/canvas-vs-svg-vs-flash.htm will give you a good start.
Edit
Without seeing your current code I can't give a precise answer but this should work:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<video src='insert-route-to.swf' id='insert-id-here' controls>
Your browser does not support HTML5 videos please Upgrade.
</video>
<button onclick="document.getElementById('insert-id-here').play()">Play</button>
<button onclick="document.getElementById('insert-id-here').pause()">Pause</button>
</body>
</html>
on button click
Response.redirect("file path");
something like:
Response.redirect("Video/abc.swf");
where "Video" is folder name which is present in project folder and "abc" is file name.

How can I change the Folder's Directory Page in HTML?

<!DOCTYPE HTML>
<html lang="en">
<head>
<title>HTML Document</title>
<meta charset="UTF-8" />
</head>
<body>
A Directory
</body>
</html>
By default when I open this link in my internet browser it shows a white page with the items in the directory. Can I change the Directory's Page. For example: http://www.aq.com/gamedesignnotes/ see how the URL points to a directory and not a HTML Document but still shows a page.
Most webhosts will show an index.html if you navigate to a directory. You could just create a new file inside your directory called index.html and put your HTML there.
Then you can go to http://yoursite.com/directory and it will show the index.html file in that directory (http://yoursite.com/directory/index.html).

It depends on your webserver. Apache HTTPD generates them using mod_autoindex which gives you some control over the apearence via directives such as IndexHeadInsert.
Your question is how to make pretty (seo friendly) urls right?
How to make http://website.com/something show a specific html page?
This can be done using mod rewrite using .htaccess files.
Here's a stack overflow topic on mod rewrite:
