Cascading
Style Sheets (CSS) is a style sheet language that permits web designers to
attach style like spacing, color, font, etc. to HTML documents. Cascading style
sheets work similarly to a template; permitting web developers to label style
for an HTML element and after that apply it to the number of web pages
required. Thus, Cascading Style Sheets (CSS) are collections of formatting
rules, which control the appearance of content in a web page. With CSS styles
you have great flexibility and control of the exact page appearance; from
precise positioning of layout to specific fonts and styles.
There are
many benefits of using CSS. One of the major benefits of using CSS is the easy
maintenance of the website. Maintenance of a website made with CSS is much
easier compared to the ones which are table based. CSS splits the presentation
style of documents from the content of documents and makes the maintenance of
the site easier. Aside from being able to make site extensive changes with no
trouble through one CSS file, the clean code it generates makes it easier to
update. Webmasters can characterize the appearance of a site in one place, and
change the whole site by changing just one file. With CSS, when you decide to
craft a change, you simply alter the style, and that element is updated
automatically anywhere it appears in the site. So, if you have to alter the
color of all pages in your site, you only have to edit one style sheet. This
saves you enormous amount of time, particularly if you have to edit each page
independently. CSS generally requires less code compared to table based. This
makes your code lighter and cleaner. Clean code makes a huge difference in
maintaining your site.
Cascading
Style Sheets Benefits and Search Engine Optimization (SEO)
Another
major benefit of CSS is that it makes your website SEO friendly. The reason
behind this is simple. The search engines spiders are actually very lethargic.
They do not go through the bundles of HTML codes to get to the indexed codes.
Font tags and tables make the HTML code very cumbersome; thus, reduce the
accuracy of the results. If you use external CSS files to design and determine
the design attributes; the HTML code will be clean and it will result to better
search engine rankings. With some knowledge of CSS you will be able to change
the code layout without destroying the actual visual layout. For instance, you
could easily make the main content of your site to show up above the header or
navigation menu in the code of your website; thus will help to show search
engine crawlers the importance of your content. I personally saw a huge boost
in rankings in fully CSS web sites. When I look at someone’s website that was
built using old school HTML code with tags such as: TABLES, TD, TR, FONT and so
on, I feel awkward and immediately convert that site to a fully table-less CSS
layout. There are many tools on the Internet that shows the actual code over
text ratio weight of your site. Do you know why? Because modern search engines
such as: Google, Yahoo and MSN love light-weighted websites. They want to see
your content; the text, not the code. With CSS everything is possible. You
practically externalize excessive code into external file, thus leaving the
actual page clean and simple.
Website
Accessibility
CSS makes
your website more accessible. The number of users browsing the web through hand
held devices are continuously growing tremendously. It is always important that
your site is accessible to them also. You can make an additional CSS document
particularly for handheld devices like cell phones, which will be called up in
place of the regular CSS document; which is not achievable with a tabular
layout. CSS benefits accessibility chiefly by separating document structure
from presentation. By separating style from markup, webmasters can simplify and
clean up the HTML in their documents, making the documents more accessible.
Increases
Download Speed of Your Website
CSS code
downloads faster than tables. Browsers read through tables twice previous to
exhibiting their contents; first to work out their structure and then to
determine their content. Moreover, tables are shown on the screen as a whole,
no part of the table will be displayed until the entire table is downloaded and
rendered. Tables support the use of spaced images to assist with positioning.
CSS generally requires less code than cumbersome 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 stored on the user’s computer; while the table layout stored
in each HTML document, must be loaded up each time a new page downloads. Also
with CSS, you can manage the order of the items downloaded into the screen. You
have the control to make the content appear previous to the slow loading
images, which is liked by most of the web users.
Cross
Browser Compatibility
For all
webmasters out there! CSS makes your website more professional. Taking the
benefits of CSS like making your websites load faster and easy to maintain, you
save a lot of time and labor. This in turn makes you lots of money. CSS makes
links of the website look more attractive and dynamic. Using CSS, you can slot
in rollovers easily and effectively, without having to use a single character
of JavaScript. Thus, CSS gives your websites a professional look. It is wise to
use CSS to jive with the current trends of the industry. All major browsers
like Firefox, Explorer, and Netscape presently recognize CSS and it is
definitely safe for web designers to use CSS now.
