信息

这是 cssplay的站长根据其最近创作的dropdown and flyout menus而改编而成的，当鼠标按顺序悬停在菜单上时，可在同一位置显示不同的页面，可在Opera, IE5.5, IE6, IE7 beta,Safari 1.3.2 & Firefox.中正确显示和工作，不兼容Mac IE5。

鼠标悬停在菜单和页面上时显示文字与图片以及链接，滚动条要加在每个页上。

样式

对于非IE浏览器来说是比较简单的，只用一个样式表。

<link> rel="stylesheet" media="all" type="text/css" href="one_page.css" />

/* common styling */
/* set up the overall width of the menu div, the font and the margins with a relative position*/

.menu {
font-family: verdana, arial, sans-serif;
width:750px;
margin:0;
position:relative;
}
/* remove the bullets and set the margin and padding to zero for the unordered list */
.menu ul {
padding:0;
margin:0;
list-style-type: none;
border:0;
}
/* float the list so that the items are in a line */
.menu ul li {
float:left;
}
/* style the links to be 249px wide by 30px high with a top and right border 1px solid white. Set the background color and the font size. */
.menu ul li a, .menu ul li a:visited {
display:block;
text-align:center;
text-decoration:none;
width:249px;
height:30px;
color:#000;
border:1px solid #fff;
border-width:1px 1px 0 0;
background:#c9c9a7;
line-height:30px;
font-size:11px;
}
/* make the dropdown ul invisible */
.menu ul li ul {
display: none;
}

/* specific to non IE browsers */
/* set the background and foreground color of the main menu li on hover */
.menu ul li:hover a {
color:#fff;
background:#b3ab79;
}
/* make the sub menu ul visible and position it beneath the first list item */
.menu ul li:hover ul {
text-align:left;
display:block;
position:absolute;
top:30px;
left:0;
text-align:left;
}
/* make the sub menu ul li the full width with padding and border. Add an auto scroll bar */
.menu ul li:hover ul li {
background:#eee;
color:#000;
padding:10px;
width:689px;
height:180px;
overflow:auto;
border:20px solid #b3ab79;
}
/*float the image left with padding and no border */
.menu ul li:hover ul li img {
float:left;
padding:10px 10px 10px 0;
border:0;
}
/* style the paragraph font height */
.menu ul li:hover ul li p {
font-size:0.9em;
}
/* style the background and foreground color of the submenu links */
.menu ul li:hover ul li a {
display:inline;
background:#eee;
color:#c00;
text-decoration:underline;
border:0;
}
/* style the background and forground colors of the links on hover */
.menu ul li:hover ul li a:hover {
text-decoration:none;
color:#000;
}

而IE还需要专门为它加一个，用条件判断加入。

/* styling specific to Internet Explorer IE5.5 and IE6. Yet to see if IE7 handles li:hover */

/* Get rid of any default table style */
table {
border-collapse:collapse;
margin:0;
padding:0;
}
/* ignore the link used by 'other browsers' */
.menu ul li a.hide, .menu ul li a:visited.hide {
display:none;
}
/* set the background and foreground color of the main menu link on hover */
.menu ul li a:hover {
color:#fff;
background:#b3ab79;
}
/* make the sub menu ul visible and position it beneath the first list item */
.menu ul li a:hover ul {
text-align:left;
display:block;
position:absolute;
top:31px;
left:0;
}

/* make the sub menu ul li the full width with padding and border. Add an auto scroll bar */
.menu ul li a:hover ul li {
background:#eee;
color:#000;
padding:10px;
width:746px;
height:240px;
overflow:auto;
border:20px solid #b3ab79;
w\idth:689px;
he\ight:180px;
}
/*float the image left with padding and no border */
.menu ul li a:hover li img {
float:left;
padding:10px 10px 10px 0;
border:0;
}
/* style the paragraph font height */
.menu ul li a:hover p {
font-size:0.7em;
f\ont-size:1em;
}
/* style the background and foreground color of the submenu links */
.menu ul li a:hover ul li a {
display:inline;
width:1px;
word-wrap:normal;
background:#eee;
color:#c00;
text-decoration:underline;
border:0;
}

/* style the background and forground colors of the links on hover */
.menu ul li a:hover ul li a:hover {
text-decoration:none;
color:#000;
}

xhtml

你会看到用条件判断来给 IE添加表格，. 其他浏览器不会用到表格，而将正常使用无序列表。文档类型声明是必须要加的，反之不能正常工作。

运行代码框

• John Constable John Constable <table><tr><td>

• Although he showed an early talent for art and began painting his native Suffolk scenery before he left school, his great originality matured slowly.

  He committed himself to a career as an artist only in 1799, when he joined the Royal Academy Schools and it was not until 1829 that he was grudgingly made a full Academician, elected by a majority of only one vote.

  In 1816 he became financially secure on the death of his father and married Maria Bicknell after a seven-year courtship and in the fact of strong opposition from her family. During the 1820s he began to win recognition: The Hay Wain (National Gallery, London, 1821) won a gold medal at the Paris Salon of 1824 and Constable was admired by Delacroix and Bonington among others.

  His wife died in 1828, however, and the remaining years of his life were clouded by despondency.

Claude Monet Claude Monet <table><tr><td>

His youth was spent in Le Havre, where he first excelled as a caricaturist but was then converted to landscape painting by his early mentor Boudin, from whom he derived his firm predilection for painting out of doors.

In 1859 he studied in Paris at the Atelier Suisse and formed a friendship with Pissarro. After two years' military service in Algiers, he returned to Le Havre and met Jongkind, to whom he said he owed `the definitive education of my eye'.

He then, in 1862, entered the studio of Gleyre in Paris and there met Renoir, Sisley, and Bazille, with whom he was to form the nucleus of the Impressionist group.

Monet's devotion to painting out of doors is illustrated by the famous story concerning one of his most ambitious early works, Women in the Garden (Musée d'Orsay, Paris; 1866-67). The picture is about 2.5 meters high and to enable him to paint all of it outside he had a trench dug in the garden so that the canvas could be raised or lowered by pulleys to the height he required.

Courbet visited him when he was working on it and said Monet would not paint even the leaves in the background unless the lighting conditions were exactly right.

Vincent Van Gogh Vincent Van Gogh <table><tr><td>

Gogh, Vincent (Willem) van (b. March 30, 1853, Zundert, Neth.--d. July 29, 1890, Auvers-sur-Oise, near Paris), generally considered the greatest Dutch painter and draughtsman after Rembrandt.

With Cézanne and Gauguin the greatest of Post-Impressionist artists. He powerfully influenced the current of Expressionism in modern art. His work, all of it produced during a period of only 10 years, hauntingly conveys through its striking colour, coarse brushwork, and contoured forms the anguish of a mental illness that eventually resulted in suicide. Among his masterpieces are numerous self-portraits and the well-known The&nbsp;Starry&nbsp;Night (1889).
