html5shiv | defacto way to enable use

I am trying to add a menu bar to my website and it looks nearly the way I want it, with the hamburger to the left and the two contact info to the right. However, only the hamburger is sticky. Also, I would like to add a background color to the menu so that when the webpage is scrolled the sticky bits sit neatly inside the colored bar. How can I make these changes?

I'm using Laravel 8 PHP framework, I need to compile JS and CSS files on localhost using node. When I'm trying to run npm run dev the error output is:

when trying to use bootstrap 5 to create a div that covers the entire height of the page my div never seems to expand despite using the 'max-height' class, is there anything preventing my div from expanding the entire page height in the code below? I also tried with raw css

I made this small program where a user types a description and then types a URL and once he clicks the upload button it starts to populate them under their respective headers. Once these headers are populated I want the user to be able to delete one or more of them if he doesn't like it by adding some sort of delete button next to populated results under URL which will delete both what's under description and URL one line at a time. This button will automatically be populated for each line when the user clicks the upload button. I know the styling isn't the greatest but these 2 headers (DESCRIPTION & URL) will be next to each other. I will style it later once I figure out how to delete.

As a start-up, we are currently developing our website. We have a bit of a programming background, but mainly in Bio-informatics, so HTML and Javascript are unfamiliar. So that's why we will ask this 'stupid' question. We are currently working in WordPress, and we have an issue with the spacing within our Footer Note. There is a dot between the items, but the spacing between these items and dots isn't the same. So it is visually uneven. So the dot has to be there, but the spacing should be even. We have looked at the code, but we can't find this spacing problem. This photo represents the problem, to show it visually.

Besides that, we use the following code for the Footer

I am making a form and the client wants the input box to change once clicked and the client wants that change to stay once it has been filled and they have moved to the next input box. Is there anyway to do this? Preferably with only HTML & CSS rather than incorporating any JS. If incorporating JS is absolutely necessary I would not mind that and we can definitely do that.

I can attach the code if it is necessary. I am just wondering if there is a way to maintain the state once you move to no state.

pic 1 is how the form looks empty. pic 2 is how it looks when the form is filled and how the client wants the input box to look after you have left the input box to the next one. pic 3 is how it looks when you leave the input box to the next one.

here is the code:

Good day stackoverflow community. Have a non trivial question. For displaying web content we are using ActiveX. We decided to switch to QWebEngine, but were faced with the problems:

ActiveX allows us:

1. save HTML anchors in QAxObject
2. listen to anchors click events
3. extract and change anchors properties ("id", "href")

Example of code:

For example, if we enter any email in the form, we receive an email spoofing error when submitting the form. However, the form sends without error if we enter an email from the domain of the website.

How do we change the email to be sent from the domain instead of the email submitted from the form?

Thank you in advance for your time and skill. 🙏🏼

I need to create a method that reads a html file then display the number of word occurrence.

This is what I did:
