The World Of CSS Web Design
css, web design
Even though CSS was first introduced in the middle 1990s, it did not become a normal tool among web designers and web masters until more recent years. This is unfortunate, because there are millions of poorly web designed websites cluttering the internet that could be easily improved with the help of CSS.
So what exactly is CSS? CSS is anshort form that stands for Cascading Style Sheets. The term Cascading Style Sheets make up of two things. Firstly, the style sheets are cascading. This means that manifold style sheets can be used for a single webpage. as well, the term “cascading” also refers to the way a style is strong-minded in the event that more than one rule matches a single element. The second thing that is indirect by the name Cascading Style Sheets is that the purpose of CSS is to style WebPages. Whereas the purpose of HTML (or XHTML) is to define the structure of a webpage, the purpose of CSS is to define the appearance.
The reason that so many WebPages have broken layouts in different browsers is because they try to use HTML to control the all structure and presentation of the web page. The most common misused of HTML is attempting to use tables as a presentation method. Although you may be able to achieve the look you want in a few browser, your web page will look broken and distorted in many other browsers. The only time that your tables should be used is to hold a set of data such as the results from a scientific experiment. If you do have a legitimate use for tables on your webpage, you can even use CSS to style your table and make it more good looking.
By taking your time to learn CSS, you will be able to create a webpage that looks much more consistent across a deferent of browsers.
Reason Why CSS Is Good For Your Web Site
Keywords :web design, development reason
Cascading Style Sheets (CSS) are used within the HTML behind your Website as a way of controlling how each page is lay out and what elements on it look like. For example, you can use CSS to make headings in your copy a standard size across the whole of your web site.
CSS has been around for more than a few years and is supported by all the major browsers available today, including Internet Explorer for the PC and Mac, Firefox, Safari, Opera and Chrome.
Below are several benefits of CSS to control your Web site
Makes your Web pages snappier
By using CSS and HTML your code will match to standards like ‘XHTML Transitional’ or ‘XHTML Strict’ you can decrease the ‘render time’ of your web pages. This is the time it takes between downloading the web page and actually displays it on screen to your Websitevisitor.
When using tables for layout the traditional option to using CSS and ‘font’ tags to control how the text on the page looks, the browsers have a lot more work to do before they display the web page. Using CSS and the proper DocType for the web pages means the browser knows what to expect from the code and can display it much more quickly.
In practice, converting to a standards based CSS layout on one client’s Website reduced the time it took the web page to display by almost a district of a second. Although this is a very small amount of time, it is more than enough to make a Website feel much more snappy and responsive, helping it give a good impression to your potential customers.
Makes your Web site quicker to update
As well as making your web pages display faster, CSS makes it easier to make worldwide updates to your Website. Say you’re having a small change in corporate image and want all your page headings changed from yellow to blue. With CSS scheming how your headings look, that means changing the color in one file and the whole site shows the change, a two minute job rather than having to edit all pages on the your site.
This flexibility gives you the opportunity to do more with your Website. For example Want to show your support for Red Nose Day? Again, one file change can put a little red nose next to all of your headers, turn the text redcolor and even make them display in a ridiculous typeface. Turning them back to normal for the next day is, once again, a simple file change.
Good for Search Engine Optimization
Because using CSS removes lots of HTML from your pages as layout and the look of text is controlled through the CSS file, it makes your textual content much look more prominent within your HTML. This means the search engine spiders can without difficulty find your textual content, and that your content is generally displayed in one block, rather than being split up into less clear chunks by HTML just to fit it in to your design.
Using ‘semantically correct XHTML’ that isheading tags around the headings and sub headings in your copy, andstrong or bold tags around your content you wish to highlight tells the search engines those words are the most important on the web page. This helps give the web page a boost for searches which match the words which are marked as more important in this way.
Helps in passing the Disability Discrimination Act
Using good CSS and XHTML it makes it easy for people with disabilities to change your pages the way they may need to for easy reading. This may be through increasing or decreasing the font size, or having it read to them from side to side a screen reader. The clean page coding that goes along with using CSS means screen readers can easily navigate through your web page and find the texture content, giving a good experience to visually impaired users.
Using CSS and XHTML also helps you comply with the UK Disability Discrimination Act rules for accessible Websites. This is a respected sideeffect of using this kind of coding and takes no extra development time to be obedient.
Helps browsing from different devices
As well as it helping screen readers, using CSS means alternative devices like mobile phones and PDAs can show your content effectively and easily to navigate. Even though the current market in the West for browsing the Web through mobiles is small, it is growing and by using CSS you can create a Website which is easily viewable on these devices with little additional extra effort,. So as more people are using them it will be simple to convert your web site to work with current or future devices..
at this time, Web browsers treat CSS to some extent differently, so when your Website is created you may need slightly more cross browser testing, and you will need to find a Web designer who understands how to build a web site in CSS correctly. Most professional developersand web designers are now seeing the important of creating standards based CSS sites, but it is worth ensuring that anyone you hire to make your Website does know CSS before starting a new project.
But the down sides are small when compared to the immediate and ongoing inpoetant benefits of a CSS-based Web site.
Even though CSS was first introduce in 1990s, it did not become a mainstream tool among web designers and masters until more recent years. This is untoward, because there are millions of poorly web designed web sites cluttering the internet that could be easily improved with the help of CSS.
So what exactly is CSS? CSS is an short form that stands for Cascading Style Sheets. The term Cascading Style Sheets infers two things. Firstly, the style sheets are cascading.
