<body>
here is index.html

If it's frameset, it doesn't need the body.

Error:
Workaround: Left has no resources and a 404 error has occurred.
When we are doing the frame, frameset can be understood as TR line, frame can be understood as TD column, there are multiple columns in one row is allowed.
Moreover, when we write SRC, the system will look for resources from under your folder by default, so it is best to write the name of the website first, then paste it.
?
How to remove the line inside the frame border="1" border = "0" can be
In the framework if not all the display, we can set the next frameset inside the rows = "15%,14%, xxxx"; Modify the scale.

HTML5 + CSS3 Very cool

?
An interface does not change in the background and becomes mostly style.
CSS is embedded, written in the style in front of the HTML.
<style>
a{
Font-size:30px
}
. One
{
Font-size:30px;
Color: Red;
Font-family: Official script;
}
. the
{
Font-size:30px;
Color: Red;
Font-family: Official script;
}
. Three
{
Font-size:30px;
Color: Red;
Font-family: Official script;
}
?
#first
{
Color:Red;
}
#secoed
{
Color:Blue;
}
</style>
It is best to use the outer-embedded type, can be directly referenced.
<link rel = "Sytlesheet" type= "Text/css" href= "Css/day4.css"/>

Second, JavaScript introduction
Basic syntax: Case sensitive, variable type not divided, unified var. You can omit semicolons at the end of each statement
Keyword: break,case,do,else,for,if,function,retrun,while,catch,continue,default,delete
Variable declarations with C + +
Control statement: If IfElse switch
Alert pops up a dialog box
<script language
Embed JavaScript
???????? <scripttype="text/javascript">
???????? function logincheck ()
???????? {
???????? Alert (" I'm out ")
????????}
???????? </Script>
?
for JavaScript statement, the end must not have, semicolon, or will error, and wrong a full error.
???????? <scripttype="text/javascript">
???? function Logincheck () {
???????? var UserName = Document.login.userName.value// this thing needs a layer of peeling down, where document is the entire Document object, login Yes form name username is text text box
of the name;. Value is the value that gets the text box you entered.
???????? var password = document.login.password.value
???????? if (userName = = "") {
???????? Alert (" user name cannot be empty ")
???????? returnfalse
?
????????} Elseif (password = = "") {
alert (" password cannot be empty ")
return false
????????}
???????? Alert (" I'm out "+username + password)
????}
This is called the scripting language, in fact, the script statement JavaScript is the simplest one, do the user password verification is more appropriate.
What's more, when we do the page, we have to verify that it must be verified at the time of submission. We need to add a click event.
<inputtype="Submit"value=" Save "name=" btn "
OnClick="return Logincheck ();" >
If there is a return in the function, it is used directly return function (); can be.
