HTML Horizontal Line
<HR/> Tags Create horizontal lines in the HTML page.
The HR element can be used to delimit content.
HTML AnnotationsYou can insert comments into HTML code, which improves readability and makes your code easier to understand. The browser ignores comments and does not display them.
Note This is written:<!—-comment text--
Note: The opening parenthesis (the left parenthesis) needs to be immediately followed by an exclamation mark, which is not required until the closing parenthesis (the right parenthesis).
tip: using annotations wisely can help you with future code editing efforts.
HTML WrappingIf you want to wrap (a new line) without creating a new paragraph, use the <BR/> Label:
<p> content <br/> content <br/> Content </p>
The <br/> element is an empty HTML element. Because the close tag doesn't make any sense, it doesn't have an end tag.
HTML output-Useful hintsWe cannot determine the exact effect of HTML being displayed. The size of the screen, as well as the adjustment of the window, can result in different results.
For HTML, you cannot change the effect of the output by adding extra spaces or line breaks in the HTML code.
When a page is displayed, the browser removes extra spaces and blank lines from the source code . All contiguous spaces or blank lines are counted as a single space. Note that all consecutive empty lines (line breaks) in the HTML code are also displayed as a single space.
