Snippet:just for your own html5 template

Published on March 31, 2013, by in Css, Html5.

I find something fantastic snippets for web designers, actually i am new to html5, the snippets below may be parts of your base template.
1. Basic html5 template

Internet Explorer has many rendering engines ready for use. What this line of code basically does is force IE to use the most up to date rendering engine that it has available, so that your pages will render as well as possible. It then goes on to talk about Chrome Frame. Chrome Frame is a plugin for IE6, 7, and 8 which brings all the rendering, and js power of Google Chrome to IE. If the user has it installed, we render our site using it.

2. Conditional body tag

3. jQuery loading fallback
A vast majority of sites these days make use of the jQuery JavaScript library. A vast majority also make use of Google’s hosted version of the library for faster loading speed’s, and better cross site caching. However, what if there is ever a problem and jQuery is not loaded from Google? Well here is your backup. What it basically does is check if jQuery is loaded from Google. If not, then we load it locally from our own version of jQuery.

4. Html5 ready reset
Plenty of you will have used Eric Meyer’s css reset before now. It is included in many frameworks and so on, like 960.gs. This is a revamped version of that reset, that brings it into the present with full support for html5. It sets all the new structural tags as block level, and resets all their default styling as expected.

5. Force scrollbar
Sometimes, pages can be shorter than the browser view-port, and when you load a page on the same site that has longer content and uses a scrollbar, content can jump side to side. By forcing a scrollbar no matter the height of our content, we stop this small, but annoying issue.

6. Aligning Labels
Alignment of labels with their relevant inputs can be a horrible task to achieve in older browsers. This snippets solves that for us by making it consistent across browsers!

7.Print styles
Any decent site should be print ready, as even though we live in a technology driven time, people still like to have a hard copy of some information. This snippet firstly uses a css media declaration, allowing you to include this in your main stylesheet, and not having to place another link in the head of your document. This benefits load time, as even when the page inst being printed, a browser will always download that extra css file, generating an extra http request. The snippet then goes on to include some useful print styles such as printing our link urls, and so on.

8. X-UA-Compatible Server sided
This is the same as the html version mentioned above, forcing the latest rendering engine in IE, and Chrome Frame if it exists. The benefit of including this in your .htaccess file is that it saves you having to declare this in the head of each and every html document you produce.

9. Gzip compression
Gzip compression allows us to drastically reduce out file sizes. This .htaccess snippet does the gzipping for us.

I am learning Laravl and Backbonejs for a few days, someone has the same preference please have an email with me, i want to build something special for Chinese programmers, and the new project is on its way now.

Use command line, input this command:

Screenshot:

Then you see the log_slow_queries variable is set to off.
Otherwise, you can step this blow:
Find your my.ini file, then add the statement blow [mysqld], be careful of this tip.

Or you can use command like this, but you need the root user to do this.

I use the first method, and the second had not been tested.
You have set the log_slow_query to on, min query time to 2 seconds and the log file location.
After done this, you should restart your mysql service, and use the command check if your settings take effect.
3.Test the settings
You can test your settings this way:

The result shows that:
1.Your statement start query time
2.Execute user
