How to use frameset framework? Use of frameset frame attribute
The content of this article is about how to use the frameset framework? The use of frameset frame attributes has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
frameset is a frame tag in HTML, used to define a collection of multiple frames, each frame has an independent document. Note two points when using
frameset:
① Cannot be used in body
② When there are frameset and body elements in the same HTML browser The frameset element will be used first
The standard attributes of the frameset element are: rows, cols
rows represents row display, its value can be px or % or *, when When rows="120,*", it means that the first page occupies 120px, and the second page will occupy the remaining space.
cols represents column display, the value is as above
frameset frame example is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Hello!Word</title>
</head>
<frameset rows="25%,50%,25%">
<frame src="HTML/html1.html">
<frame src="HTML/html2.html">
<frame src="HTML/html3.html">
</frameset>
</html>Code interpretation: We defined a frameset element and introduced three The frame page sizes are 25%, 50%, and 25% respectively. Displayed in rows, the first html1 page accounts for 25% of the entire page, html2 accounts for 50% of the entire page, and html3 accounts for 25% of the entire page. Sub tags Used to link to html pages
Running result graph:
##cols is also used in the same way
At this time we will have a question, what if there are no rows and cols attributes in the frameset? ? Practice is the only criterion for testing truth! ! ! Through practice we have concluded that when the frameset does not have the rows and cols attributes, it will only display the first HTML page you connect to The body can be included in the sub-tag of the frameset< noframe>, used to handle information when the frame cannot be displayed. But this tag is generally not used, because modern browsers support frameset. The frameset tag and the tag can achieve the navigation bar effect! ! !
