validator.nu

I want to write a xUnit test for ValidatorCreateAsync method and here is the method:

I am trying to send a local html file from my computer to the https://validator.nu/ from W3C to validate it. I found this curl command which worked perfectly fine in terminal:

I try to use the reactive form and I need to create only the key for each item that is filled But because the first moment is created, if the field is not full, it sends null While I want a field that is not empty to be sent at all my code is:

I'm trying to check a website via w3 validator, but it always fails with this error:

End of file seen without seeing a doctype first. Expected .

It's seems that it fails getting source code of the website for some reason.

However, if I add Accept-Language parameter (check this request), it will validate correctly. It's not only problem with w3 validator, for example, facebook parser, responsible for showing website preview, also doesn't see the source code.

The website uses Codeigniter php framework. Could it be the problem? Any ideas how to solve the problem?

I'm doing a web application in Angular 8. I have a form with just 1 input to enter a 5 digits number (as string). I want to validate that this number is unique in the database.

I have tried to implement an async validator. I need to pass to it a few variables, so, I have added the validators later dynamically.

I have an intractable, at least for me, HTML/CSS problem. Here is a bit of a web page I'm currently developing:

(The whole page is here: http://www.professorbrown.net/ but has now been changed as suggested in the accepted answer.) Note that the "fine print" at the bottom has the same line spacing as the body copy, and I can't fix it. It looks the same in Chrome, Firefox, and Edge, so it has to be an error in my work.

The CSS is: .fine {font-size: 1rem; line-height: 1.1;} The markup is .

Using the inspector function of both Chrome and Firefox shows the computed CSS for font-size as 10px, which is correct, and the line-height as 11px, which is what I intended, but clearly not what's displayed. Measurement says the displayed line height is about 32px, which is the same as the body copy above the fine print. Margin, border, and padding for the fine print are all zero. HTML and CSS validate using validator.nu and Jigsaw. There are style sheets from Skeleton, Superfish, and Slick linked in. I've commented them out one by one with no change in the error.

Please tell me what I've done wrong or give me some help with further debugging.

(Note: This is still a development project, so TLS is not enabled and the images have watermarks because I haven't licensed them yet. I know both things must be done before "production.")
