I have a firebase hosted Flutter Web application which is a game. Since the URL for the Firebase hosted site (https://jw-daily.web.app) is difficult to remember for users, I bought a domain name (joinedwords.com) and redirected the URL to the firebase hosted site.
Problem is that when I type the domain URL i.e. joinedwords.com, the website renders in only half the height like below:
However, if I type the original URL (https://jw-daily.web.app) in the browser, the webpage renders in full like below:
All that I have done is with my domain provider, I have set a forward with masking of joinedwords.com => https://jw-daily.web.app/
I looked up all the other solutions around why a webpage is rendering in half. However most of them are asking to make changes to the code and I don't want to do that since the original URL is working fine. Incidentally this issue is happening only on mobile browsers and not happening on desktop. In desktop, the website renders correctly regardless of which URL is typed.
Please suggest if you are aware of how we can solve this problem. Here is my index.html file.

Found an answer to the issue I was facing. Here is the link to the same:
Bootstrap Responsive Design Fails with Web Forwarding
This is because you are using a framed redirect which essentially loads up the target website in an iFrame. Doing so loses any responsive capabilities. What you are best doing is changing your web forwarding method to actually forward to the new URL using a non-framed redirect. This will then properly load up the target URL in the users browser and all the responsive capabilities that go with it.
I made a Pwa with Flutter Web and I set as color on the whole project: # 8C3144. On Index.html I have black-translucent so also the status-bar in ios became # 8C3144, but it continues to remain black. I don't understand what I need to change, I don't think the problem is in the Flutter project

In the in index.html add this in the head:

}
</style>
I am looking to scrape player prices on https://www.fanteam.com/participate/138905/new/e30= using Python and Selenium libraries. I have used the following code:
url = 'https://www.fanteam.com/participate/138905/new/e30='
options = webdriver.ChromeOptions()
options.add_argument('--lang=en')
driver = webdriver.Chrome(chrome_options=options)
driver.get(url)
But I can't get all the players with prices, because I can't find any element on the page(see the picture below
players with prices).
There is HTML of this site:

Any code like
el = driver.find_element_by_xpath("//div[#class='player-list']")
return me the error:
NoSuchElementException: Message: no such element: Unable to locate element: {"method":"xpath","selector":"//div[#class='player-list']"}
But when I inspect an element I can see it in the browser.
How to click any element on the page?
The website you are trying to scrape has a shadow-DOM in its html and any html present inside it cannot be accessed and that is the reason you are getting NoSuchElementException.
Currently, selenium does not support the shadow DOM automation, so you need to use javascript in this case to scrape the data.
To get the data using javascript, you can use:
JavascriptExecutor js = (JavascriptExecutor) driver;
String return_value = (String) js.execute_script("return document.getElementByXpath('xpath').innerHTML");
References for the shadow DOM:

UPDATE
This generates error
<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Roboto%20Condensed|Source%20Sans%20Pro" />
This Works
<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Lato" />
<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Roboto%20Condensed" />
When i add | to add multiple fonts it generates error so should i use multiple <link> tag to add fonts or ?
Confused about this is as below links is generate by on Google fonts font use on website
https://www.google.com/fonts#UsePlace:use/Collection:Open+Sans|Roboto:400,700,400italic|Roboto+Condensed:400,300|Lato
Your example code working with JAVASCRIPT NOTATION
LINK and IMPORT may not help to eliminate the VALIDATION error - so please try with JAVASCRIPT notation it works well without any error.
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
<meta charset="utf-8" />
<script type="text/javascript">
WebFontConfig = {google: { families: [ Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic|Montserrat:700|Merriweather:400italic|Roboto+Condensed|Source+Sans+Pro|Droid+Serif|Open+Sans+Condensed|Oswald|Molengo|PT+Sans|Droid+Sans ] }};
(function() {
var wf = document.createElement('script');
wf.src = ('https:' == document.location.protocol ? 'https' : 'http') +

wf.type = 'text/javascript';
wf.async = 'true';
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(wf, s);
})();
</script>
</head>

You will need to substiture & sign with &
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
<meta charset="utf-8" />
<meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1, maximum-scale=1" />

You may please use JAVASCRIPT notation for including the fonts from google
<!DOCTYPE html>

<meta charset="utf-8" />
<meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1, maximum-scale=1" />

Few more suggestions
Always include doctype at the top of HTML page
Try the IMPORT and JAVASCRIPT alternatives to include the fonts.
Please use your own google font - to avoid typos I tried with new fonts from google.
The character | is not allowed in the query component (nor anywhere else in a URI). It would have to be percent-encoded with %7C.
So
http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic|Montserrat:700|Merriweather:400italic|Roboto+Condensed|Source+Sans+Pro|Droid+Serif|Open+Sans+Condensed|Oswald|Molengo|PT+Sans|Droid+Sans')
should be this URI instead
http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic%7CMontserrat:700%7CMerriweather:400italic%7CRoboto+Condensed%7CSource+Sans+Pro%7CDroid+Serif%7COpen+Sans+Condensed%7COswald%7CMolengo%7CPT+Sans%7CDroid+Sans')
There is a space in the string near the end
PT Sans|Droid Sans')"
should be escaped as:
PT%20Sans|Droid%20Sans')"

Can anyone help me with this problem? Thanks a lot!
In Chrome you can add: --allow-file-access-from-files to the Chrome command line to allow local file to be read from local HTML pages.
You can also bundle your code up as Chrome Extension and get local file access that way.
Or upload the HTML files to a Server as already mentioned.
