You just need to understand the very basics of what makes up a website inside. It's a system of individual software components. You can see them through the eyes of a web developer by pressing CTRL+U in Chrome. Then you can easily see what makes a website "sticky":
HTML code – or the language that displays the content of the page (headings, texts, paragraphs, links)
in the HTML code there are links to other resources – images, videos – at designated places
and all of this has to move thanks to additional elements – for example, JavaScript libraries that provide animations, different fonts, mobile display
Links to images and additional elements (Javascript elements) are the alpha and omega of the Internet and at the same time a stumbling block in terms of data protection. A link to such an image or script can lead not only to your own website, but also to a foreign domain over which you no longer have any control . Thanks to this idea, the Internet itself was tunisia phone number list created, where thanks to the principle of interconnectedness, anyone can place a video from Youtube on their website , connect to another website, or launch, for example, a specific functional application via JavaScript code . All this simply and in a few seconds . That is why today there are beautiful websites, with beautiful functions, and their production costs a fraction of what everyone would have to solve again and again independently.
Every website today is literally crawling with applications that are uploaded from foreign places. Examples?
If you want to have a nice font on your website, usually all developers use Google Fonts - an external JavaScript library
Share buttons on Facebook, Twitter, LinkedIn – external JavaScript library from the given social network
Tracking user behavior and mouse movements – external JavaScript library
If you want a fast website – you upload your images and libraries from a CDN – an external location over which you have no control
As you can see, using external applications or uploading parts of a website from somewhere other than your own website is completely normal.
And it is precisely this possibility of web interdependence that can be a problem. Application codes that help with something on the web allow you to work with the website almost as well as your own application, which is located directly and only on your own website. So you have to think carefully about who you let on your website. Foreign code on your own website is the same in the online environment as giving the keys to the company to the postman because you trust that in good faith he will just unlock the door, put the package outside the door and immediately leave again.
Currently, there is no mechanism that could limit these foreign online technologies and prevent them from doing whatever they see fit with your website. For example, changing the content, website graphics, spying on your visitors, identifying potential clients, and perhaps even selling this information to competitors. The only current protection is to consistently read the terms of service that you put on your website. With special attention to those that are too cheap, or, God forbid, free. Our client had exactly such an “innocent” piece of foreign code , recommended by someone, for a great price , on his website. He didn’t remember how long.
