Why is download speed so important?
As we all know nobody wants to wait everybody in this word wants to get everything in flash…so tell me Do you like to wait for pages to download? i do not think so,and if is it so…just go through following zombie steps…..
1. Design your pages with Stylesheet(CSS), not tables
CSS downloads faster than tables because:
Browsers read through tables twice before displaying their contents, once to work out their structure and once to determine their content
Tables appear on the screen all in one go - no part of the table will appear until the entire table is downloaded.
CSS generally requires less code than tables
All code to do with the layout can be placed in an external CSS document, which will be called up just once and then cached (stored) on the user's computer; table layout, stored in each HTML document, must be loaded up each time a new page downloads
With CSS you can control the order items download on to the screen - make the content appear before slow-loading images and your site users will definitely appreciate it …(I dnt abt about others..but I really do.)
2. Don't use images where you only wants to display text
This is where CSS comes into the picture.There is no need to use image where u want only text just use CSS and feel the power. Have a look at this code:
3. Use shorthand CSS properties
Font
Use:
Font: 1em/1.5e, bold italic serif
...instead of
font-size:1em;
line-height:1.5em
font-weight:bold;…etc.
Border
Use:
Border:1px solid #000000;
...instead of
border-width:1px;
border-color:#000;
border-style:solid;
Same things can be applied for background, margin, padding…..
4. Minimise white space and comment tags
Every single letter or space in your HTML code takes up one byte(oh my goshhhhhhhh). It doesn't matter but when considered along with all the spaces it may go higher than expected.
5. Use relative calls rather than absolutes
Try to avoid absolute call ups as they take up more space. An example of an absolute call up is:
. Much better would be
. But what if some files are in different folders to other ones? Use these shorthand properties:
- Calls up http://www.URL.com
- Calls up http://www.URL.com/filename.html
- Calls up http://www.URL.com/directory/filename.html
- Calls up index.html within that directory
- Calls up index.html one directory above
- Calls up filename.html one directory above
- Calls up index.html two directories above
6. Put CSS and JavaScript into external documents
To place CSS in an external document use:
To place JavaScript in an external document use:
Any external file is called up just once and then cached (stored) on the user's computer. Instead of repeating JavaScript or CSS over and over again in HTML files, just write it out once in an external document.
7. Use / at the end of all links to directory
Don't do this:
http://www.myBlog.com/zombieDo this instead:
http://www.myBlog.com/zombieWhy? If there's no slash at the end of the URL the server doesn't know if the link is pointing to a file or to a directory. By including the slash the server instantly knows that the URL is pointing to a directory and doesn't need to spend any time trying to work it out…isn’t it amazing…....
I hope this will help u people…as it helped me also…so happy CSSingggggggggg….
