This programming language can do, but is not limited to, the following:
- It can detect if a user is active or idle through touch screen presses, cursor movements, mouse clicks, scrolls, and keyboard input.
- It can store data, such as previous site activity and webpage preferences, on the client’s server.
- It can enhance a website’s design by creating a navigation tool like pop-up menus or drop-down menus.
- When it comes to online forms, such as registration forms and login credentials, it can provide basic validation and data format validation.
- Interact between different websites since each website has its own unique server and programming language.
- Enable or control microphones or webcams without asking the user’s explicit permission to do so.
- Read or write anything on a client’s hard disk or execute programs on a user’s computer.
HTML handles all the content of a website, including text, images, page titles, and other content. CSS, on the other hand, specifies the layout of the content. This provides the dimensions of images and the font color, type, and size of texts. It customizes the content from HTML and encompasses most of the design factors of a webpage.
Some websites either use dynamic code or static code or both. Dynamic means that the content updates depending on a given circumstance—for example, the current foreign exchange rate. A static code, on the other hand, only displays content that never changes.
