Why does the browser automatically have padding on the sides?

Question

css

Why does the browser automatically have side margins when writing HTML code?
How to remove them please give advice.

Answer 1

The browser by default sets page indentation: css-property marginfor html-tag body.
To remove unnecessary indentation, it is considered bad practice to write the following css:

* {
    margin: 0;
    padding: 0;
}

Reason - Adds unnecessary code to elements. Most already have zero default indents, while others (for example, headings, lists) usually have their own.
Experienced guys reset indents and other styles with reset.cssor normalize.css. Cons of this trip:
Yandex advises not to use asterisk selectors, not to reset styles, but to write universal blocks. Your case:

.page {
    margin: 0;
}
