QUESTION
I had an issue with small images loading very slowly so I figured I should try to preload it to the browser cache. I looked it up and found numerous ways to asynchronously preload the images but two things remained unclear. Let's say I have an array of images file names (assume each element is the correct full path)
...ANSWER

I used
to achieve preloading.
I imagine your JavaScript function does the same. If so what happens is that the browser loads all the images before it displays the page and therefore it can display the images without interruption.
To be able to check if that's really what's happening "Inspect" your page and in the sources tab you should be able to see all the files the browser has loaded up including your images and it uses the same file hierarchy as you did in your code.

I have been struggling trying to make TailwindCSS work with Angular. I followed some tutorials and looked in the documentation of Tailwind. For some reason in certain places in the Angular 9 application it's working and in lazy loaded modules it's not (so it seems)!
So first thing I did was following and implementing these tutorials:
https://dev.to/seankerwin/angular-8-tailwind-css-guide-3m45
https://dev.to/beavearony/building-tailwind-css-in-an-angular-cli-project-e04
I know for sure I have these installed correctly because of the following: My sidebar(app-sidebar) is having the correct css and styling! But the page I'm on loaded through the is not.
I will provide you with my app-routing.module, and the default layout and the dashboard component. On this Dashboard the tailwindCSS is not loading. (Funny thing: if I add an H1 element with no class, no nothing I see this element on the dashboard page!) The other elements which contain some kind of tailwindCSS class don't. Also if I drag-and-drop through the content of my dashboard component to outside this dashboard component I see my elements, although without any styling. (I do this with Chrome DevTools)
app-routing.module.ts
...ANSWER
Answered 2020-May-14 at 11:35So I have figured it out. There were actually two things left I had to do. First was to set the tailwindcss configuration (tailwind.config.js) and attach it to tailwindcss with the help of my webpack.config.js

This technique for preloading several images entails the following CSS:

would be ignored. However, you can use something similar since CSS3 supports multiple backgrounds:

I am still new to both phpmailer so I tried to implement zurb foundation framework to design my email template and did this as suggested in the documentation. The email were sent successfully but i get this warning and these CLIENT -> SERVER:
that prints out all the html code on the $mail->Body
tag instead of redirecting to an html page after the email was sent:
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\vendors\phpmailer\class.smtp.php:234)
Below is my code:
...ANSWER
Answered 2017-Mar-09 at 17:59Use
$mail->Debugoutput = 'error_log';
instead of$mail->Debugoutput = 'html';
will solve your problem.
header()
function must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. If any actual output is sent before header()
function call then Headers already sent
error occur. So when you use $mail->Debugoutput
as html
it generate output and error is is generated. But error_log
is not outputed, it log error in file. For more details you can see php:header manual or here
