Hello, i am still newbie on html and css, so maybe this is an stupid question, but i will try anyway
My big probleem is understanding the difference between ‘class’ and ‘id’ and when to use it? I’ve read a lot of tutorials about it, but i still can’t understand! i notice that you only can use the same ‘ID’ one time and ‘class’ more times, but my question is can i only use one time my ‘ID’ at the same element or the for whole document?
I made one website with only “classes”, is this bad?
For example, I have divided my website into different sections:
this is my exemple for services!
<section class="green">
<div class="grid960">
<div class="services"> <!--I think this needs to be "ID" or not!-->
<div class="col White">
<a href="/services.html"><img alt="service 1" height="110" src=
"../images/ico.png" width="110"></a>
<h3 class="red">Service 1</h3>
<p class="lightgray"> <p class="lightgray">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer in quam urna. Duis malesuada malesuada ultricies.
Praesent sollicitudin purus sed mi pellentesque vehicula.
</p><a class="btn btn-rounded Red" href="#">read more</a></p><a class="btn btn-rounded Red" href=
"#">read more</a>
</div>
<div class="col item2 White">
<a href="/services.html"><img alt="service 1" height="110" src=
"../images/ico2.png" width="110"></a>
<h3 class="red">service 2</h3>
<p class="lightgray"> <p class="lightgray">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer in quam urna. Duis malesuada malesuada ultricies.
Praesent sollicitudin purus sed mi pellentesque vehicula.
</p><a class="btn btn-rounded Red" href="#">read more</a></p><a class="btn btn-rounded Red" href=
"#">read more</a>
</div>
<div class="col item2 White">
<a href="/services.html"><img alt="service 1" height="110" src=
"../images/ico3.png" width="110"></a>
<h3 class="red">service 3</h3>
<p class="lightgray"> <p class="lightgray">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer in quam urna. Duis malesuada malesuada ultricies.
