Seo Master present to you:

Late last year, we released an illustrated online guidebook for everyday users who are curious about how browsers and the web work. In building 20 Things I Learned about Browsers and the Web with HTML5, JavaScript and CSS with our friends at Fi, we heard from many of you that you’d like to get your hands on the source code. Today, we’re open sourcing all the code for this web book at http://code.google.com/p/20thingsilearned, so that you can use and tinker with the code for your own projects.


20 Things I Learned was celebrated this year as an Official Honoree at the 15th Annual Webby Awards in the categories of Education, Best Visual Design (Function), and Best Practices. For those of you who missed our initial release last year, here’s a quick recap of the APIs behind some of the web book’s popular features:
  • The book uses the HTML5 canvas element to animate some of the illustrations in the book and enhance the experience with transitions between the hard cover and soft pages of the book. The page flips, including all shadows and highlights, are generated procedurally through JavaScript and drawn on canvas. You can read more about the page flips on this HTML5rocks tutorial.
  • The book takes advantage of the Application Cache API so that is can be read offline after a user’s first visit.
  • With the Local Storage API, readers can resume reading where they left off.
  • The History API provides a clutter-free URL structure that can be indexed by search engines.
  • CSS3 features such as web fonts, animations, gradients and shadows are used to enhance the visual appeal of the app.


With this open source release, we’ve also taken the opportunity to translate 20 Things I Learned into 15 languages: Bahasa Indonesia, Brazilian Portuguese, Chinese (Simplified and Traditional), Czech, Dutch, English, French, German, Italian, Japanese, Polish, Russian, Spanish, and Tagalog.


We hope that web books like 20 Things I Learned continue to inspire web developers to find compelling ways to bring the power of open web technologies to education. 20 Things I Learned is best experienced in Chrome or any up-to-date, HTML5-compliant modern browser. For those of you who’ve previously read this web book, don’t forget to hit refresh on your browser to see the new language options.

Min Li Chan is a Product Marketing Manager on the Google Chrome Team and the project curator/author for 20 Things I Learned about Browsers and the Web.

salam every one, this is a topic from google web master centrale blog: by John Blackburn and Trevor Foucher, Webmaster Tools team

Update: The described feature is no longer available.


We launched Webmaster Tools iGoogle Gadgets last month with excitement—and curiosity. Would you find them useful? We thought you might appreciate the ability to create better "dashboards" for your sites, but there's no better way to tell for sure other than to get it out so you can use it.

After our initial release, we saw clear interest in the gadgets, and plenty of suggestions for improvement. So we've spent the past several weeks working on various areas. The biggest improvements are probably for those of you with more than one site: when you add a new tab of gadgets, your gadgets will now default to the site you were viewing when you added them to your iGoogle page. Additionally, gadgets now retain settings as a group, so if you change the site for any gadget in a group, the next time you refresh that page, all the gadgets will show data for that site. And gadgets now resize dynamically, so they take up less room.

Other cosmetic and usability improvements will benefit everyone. We shortened the tab's title to "Webmaster Tools" to save space on your iGoogle page, and added a Google logo/watermark to each gadget to help distinguish them as a group. We think the gadgets look a lot better, with alternating background colors for table rows to make them easier to differentiate, and improved layout in general. The Top Search Queries gadget now shows each query's position, too.


Some of you did tell us you want a 4-column layout, but we feel that the information we display—including some fairly wide URLS—is better suited to 3 columns. If you do want 4 columns, remember that you can choose "edit this tab" yourself to select an alternate layout. Update: The 4-column layout is no longer available in iGoogle.

We really appreciate your feedback on these early gadgets, and hope these improvements make them even more useful.  

As always, please let us know what you think.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com
Seo Master present to you: This is a very nice horizontal menu in which its sub-tabs are displayed in two columns and is also made with CSS, without any scripts.
blogger navigation menu, css menu, drop-down menu
The "advantage" so to speak, is that the sub-tabs when arranged in two columns are not very long, so it will be neat and less space along. You can see an example here:


Adding A Horizontal Menu With Sub Tabs in Two Columns To Blogger

STEP 1: In Blogger, go to your "Layout" and on the "Page Elements" section.
  • Click on the "Add a Gadget" link just under your header image
  • From the Gadget's List, select "HTML/JavaScript" option.
STEP 2: Simply copy and paste this ENTIRE code into your widget. Note: Leave the "Title" section of this widget blank.
<div id='menucol'>
<div id='topwrapper'>
<ul id='top'>
<li><a href='http://YOUR URL HERE.com'>Tab 1 Title Here</a></li>
<li><a href='http://YOUR URL HERE.com'>Tab 2 Title Here</a></li>
<li><a class='submenucol' href='#'>Tab 3 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.3</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.4</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.5</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 3.6</a></li>
</ul>
</li>
<li><a class='submenucol' href='#'>Tab 4 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.3</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.4</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.5</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 4.6</a></li>
</ul>
</li>
<li><a class='submenucol' href='#'>Tab 5 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.3</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.4</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.5</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.6</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.7</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 5.8</a></li>
</ul>
</li>
<li><a href='http://YOUR URL HERE.com'>Tab 6 Title Here</a></li>

</ul>
<br class='clearit'/>
</div>
</div>
Customize your main tabs by changing the Tab Titles to whatever you want. Include a URL for each one if you want it to be 'clickable'. If not, you can just put a # sign where it says http://YOUR URL HERE.com

You can add or delete as many of the main tabs as you need, just make sure to copy the entire code for the main tab for each additional tab you want:
<li><a href='http://YOUR URL HERE.com'>Tab 7 Title Here</a>
<ul>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 7.1</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 7.2</a></li>
<li><a href='http://YOUR URL HERE.com'>Sub Tab 7.3</a></li>
</ul>
</li>
STEP 3: Now let's go a step further and add the CSS style in our Template
  • Go to Template > Edit HTML
  • Click on the sideways arrow next to <b:skin>...</b:skin> 

  • Then click anywhere inside the code area and search - using CTRL + F keys - for the ]]></b:skin> tag and just above ]]></b:skin> add this code:
/* Horizontal menu with 2 columns
----------------------------------------------- */
#menucol {
width:940px;
height:37px;
background-image: -moz-linear-gradient(top, #666666, #000000);

#top ul a:hover {

}
  • Now find (CTRL + F) this line:
/* Tabs
  • It will also have some little lines beneath:
/* Tabs
----------------------------------------------- */
  • And just below these little lines, delete the code below until you reach at:
/* Columns
----------------------------------------------- */
  • Instead of the code that you have removed, add this one:
#crosscol ul {z-index: 200; padding:0 !important;}
#crosscol li:hover {position:relative;}
#crosscol ul li {padding:0 !important;}
.tabs-outer {z-index:1;}
.tabs-inner {padding: 0 0px;}
