În tutorialul CSS pentru începători am observat şi învăţat selectorii HTML - reprezentând practic tag-urile HTML. Dar şi tu îţi poţi creea în documentul CSS proprii tăi selectori, folosindu-te de CLASS şi ID. Avantajele ar fi că poţi avea acelaşi element HTML de mai multe ori, şi folosindu-te de selectoarele class şi id, vei putea să le diferenţiezi între ele.
În codul CSS un selector “class” este precedat de punct ( . ), iar selectorul ID este precedat de “diez” (#).
#top {
background-color: #ccc;
padding: 1em
}
.intro {
color: red;
font-weight: bold;
}
Legăturile de cod catre CSS,din documentul HTML, ar putea arăta aşa :
<div id=“top“>
<h1>Chocolate curry</h1>
<p class=“intro“>Asta este replica mea atunci când gust biscuiţi de casă, cu ciocolată!</p>
<p class=“intro“>Mmm mm mmmmm</p>
</div>
Diferenţa dintre selectorul ID si CLASS e următoare : selectorul ID poate fi folosit pentru un singur element, pe când selectorul CLASS poate fi folosit pentru mai multe elemente.
Mai poţi face o mică şmecherie, de exemplu pentru un anume tag din codul HTML poţi să îi dai proprietăţile unui selector, iar în codul CSS asta ar fi scrisă “p.jump { valorile }” , in cazul ăsta tag-ul “p” va avea selectorul “jump” cu proprietăţile descrise.

In the next few months, life and time willing, I plan on starting a news website for the canal community in England, Ireland, Scottland and Wales. This is an in-progress design mock-up of where I'm headed. I'm not quite sure what to do with the bottom bit yet but I'm browsing other news sites for ideas.
The content right now is purely artificial. In most spots anyway.. Towpath Telegraph (In Progress)] Noah and Cat posted a photo:
