CSS

Here we begin a course to optimize and validate your stylesheet.css

As we know, this increasingly fashionable to have a website accessible to all,

why not?

they will not all people have access to our site smoothly and without problems.

And if this is not possible, we can not cover everything, at least the more access to our website BEST.

how nice everyone can access our website, jejeje, it seems easy, but as the stylesheet is disabled, which occurs

That is completely SQUARED page, but this is an issue which we'll talk later.

Here we are concerned that the W3C we are validating our style sheet to be more accessible and HERA and TAW, 2 websites that value and give you recommendations in order to have a web site as accessible as possible and according to rules A, AA AAA.

What is this

A, AA, AAA

is the accessibility of web pages in accordance with the recommendations of the Accessibility Guidelines for Web Contents 1.0 (WCAG 1.0).

are standards for the seaworthiness of the site, it becomes:

obsolete HTML tags, XHTML
Using color: background color and text color
script: JavaScript, Applet, Java ....
Using form labels: label label, empty controls ...
and thus a multitude of data needed for that in all cases, but so, in most cases we can allow access to most surfers

After giving a general idea of accessibility needs, we go with our style sheet:

Errors

Validate CSS

1-Go to W3C and validate our stylesheet.

W3C in this case helps us validate our leaf power both locally and from our domain.

2 "Once the results obtained, we started with the validation work, provided they do not give us ERRORS WARNINGS, something completely different but that should be taken into account.

3-Suppose we have several errors, one more special is the mouse pointer

306. moduleRowOver Invalid property: cursor hand is not a cursor value: hand

We must do, personally delete ground. Where is it?
As you can see from the error line directly gives you no line where the error in this case is the line 306
we will delete it and where it says

"cursor: hand;"

This does not affect our style sheet, or the mouse pointer, simply removes an invalid style that is the hand when you place the pointer a link.

We must heed the warnings and correct them, usually refer to issues based on the text color and background color should change these colors using similar but not identical or if we use and know the hexadecimal values vary them minimally.
