Widgets are simple tools or applications that work independently from the main content of the site. They can simply display things like clocks, calendars, music players etc. without any complex coding, which might be helpful for users or making the site look more richer!
You can add them on your site via hotlinking or uploading the widget file to your site! They are in JS (JavaScript) format and doesn't contain any other extra file. Then, you place a script tag on your HTML document to use them.
Not at all! You can use them any time you want for free.
It's not necessary, but I'd appreciate that!
Absolutely not! If I were you, I wouldn't want to use a simple widget that has a ugly looking logo or text on it!
Yes. You can customize the elements with your CSS file. You don't have to use !important rules for it. Default CSS definitions are noted in widget's own page.
Sure! Files are open source. But you can't remove or modify the credit notes and can't redistribute or sell the modified code to other people. For more info, read Terms of Service
No. They are only allowed for indie, educational or personal sites.
They sometimes get updates. So, if you use them by hotlinking, it's better to check latest updates for widgets. If you don't want to deal with it, upload the widget file to your own site :P
I'm haven't tested it, but I guess so. I'm using Google Chrome, and haven't got any error for now.
You can contact me from my site's chatbox, guestbook or my neocities profile.
Probably not. But if you do, you can download the widget code and upload it to your own site. It will work that way.
