CSS, since its version 2.1, offers a relatively unknown counter system due to an old incompatibility on IE. Some of you will probably defend the following position: CSS is not made for that, you have to use JavaScript. So be it! But know that it exists, and discover how to use it. Small introduction! <\/p>\n
This blog post is a translation from the original french article written in 2012<\/strong>. Keep this history in mind \ud83d\ude42<\/p>\n As I told you, the counters exist and are defined since CSS2.1 by the W3C<\/a>. The arrival of CSS3 allowed to complete the definition a bit and to include it in a module called “Generated and Replaced Content<\/a>“.<\/p>\n In this article, we will play with three properties and one function:<\/p>\n Here we’ve got two initialized counters: Here we have two counters redefined: Here our two initial counters will be increased by 2 for count1 and 4 for count2.<\/li>\n In this example, the content of a About the style of the counter, it is possible to specify the values “disc”, “circle”, “square” and “none”, so it is possible to generate nothing. I haven’t found any real use case for these values yet.<\/p>\n As I write these lines, the The simplest way to present those CSS Counters is to give you a well-organized document with a few headings at different levels. The code used in HTML is relatively simple: make sure you have The CSS is relatively short when it comes to counters, you just have to pay attention to the details: when counters are initiated and incremented.<\/p>\n You’re going to tell me: What’s the point since the \n<\/p>\n\n There is a lot of stuff to know about lists, especially Don’t hesitate if you have any question.<\/p>\n CSS, since its version 2.1, offers a relatively unknown counter system due to an old incompatibility on IE.

counter-reset<\/code>: this property allows you to initialize a counter (create it). To do this, you need to fill in one or more counter names followed by its initial numerical value.
\nExample:
\ncounter-reset: count1 4 count2 0;<\/code><\/pre> count1<\/code> which starts at 4, and count2<\/code> which starts at 0.<\/li>\ncounter-set<\/code> : this property allows you to redefine the value of a counter, without creating a new one. To do this, fill in one or more existing counter names followed by its new numerical value.
\nFor example:
\ncounter-set: count1 0 count2 3;<\/code><\/pre> count1<\/code> which restarts at 0, and count2<\/code> which restarts at 3.<\/li>\ncounter-increment<\/code> : this property allows you to increment a counter. To do this, enter the name of one or more counters, each followed by the number to be incremented. Without number following the counter name, the increment will be +1 by default.
\nFor example:
\ncounter-increment: count1 2 count2 4;<\/code><\/pre> counter()<\/code>: this function associated with the pseudo-element ::before<\/code> or ::after<\/code> and the content<\/code> property allows you to insert the counter in your page. This generates a dynamic content. It takes one parameter and a second optional parameter. The first one is the counter name, the second one is the counter style<\/a>. (same values as list-style-type<\/code>)
\nFor example:li::before {li<\/code> element will be preceded by a content type of “04 -“.<\/li>\n<\/ul>\ncounter-set<\/code> property is not recognized by any browsers but Firefox.<\/p>\nCounter CSS D\u00e9mo<\/h2>\n

\nYes, that’s true, but the use of the generated content allows to apply richer styles thanks to CSS.
