What is the form of an HTML comment?

In HTML, comments are marked by `<!--` at the beginning of the comment and `-->` at the end of the comment. Any text in between these two markers is considered as a comment and will be ignored by the browser when rendering the HTML page. Here's an example:
```
<!-- This is a comment in HTML -->
```
Comments are often used to leave notes or explanations for other developers who may be working on the same codebase. They can also be used to temporarily disable a piece of code without having to delete it.

What is the format of an inline style sheet?
An inline style sheet is defined using the `style` attribute within an HTML element. The format typically looks like this:
```html
<element style="property: value; property: value;">
```
For example, to set the color of a paragraph to red, you would use:
```html
<p style="color: red;">This is a red paragraph.</p>
```
Note that multiple CSS properties can be set within the same `style` attribute by separating them with a semicolon.
what is the usage of call in makefile?
In a Makefile, the call function is used to invoke a macro with arguments. It allows you to define a macro with parameters and then call that macro with different arguments throughout the Makefile.
The syntax for using the call function is as follows:
```
$(call macro-name,parameter1,parameter2,...)
```
Here, "macro-name" is the name of the macro you want to invoke, and "parameter1", "parameter2", etc. are the parameters that you want to pass to the macro.
For example, suppose you have defined a macro called "print" that takes a single parameter and simply prints it to the console:
```
define print
@echo $(1)
endef
```
You can then use the call function to invoke this macro with different arguments:
```
$(call print, "Hello, world!")
$(call print, "This is a test.")
```
This will output the following to the console:
```
Hello, world!
This is a test.
```
