[css] Does height and width not apply to span?

Total noob question, but here.

CSS

.product__specfield_8_arrow {

    /*background-image:url(../../upload/orng_bg_arrow.png);
    background-repeat:no-repeat;*/
    background-color:#fc0;
    width:50px !important;
    height:33px !important;
    border: 1px solid #dddddd;
    border-left:none;
    border-radius:5px;
    -moz-border-radius:5px;
    -webkit-border-radius:5px;
    border-bottom-left-radius:0px;
    border-top-left-radius:0px;
    -moz-border-radius-bottomleft:0px;
    -moz-border-radius-topleft:0px;
    -webkit-border-bottom-left-radius:0px;
    -webkit-border-top-left-radius:0px;
    margin:0;
    padding:2px;
    cursor:pointer;
}???

HTML

<span class="product__specfield_8_arrow">&nbsp;</span>?

Fiddle

Basically I'm trying to emulate a button, make a span (or something) look like a button next to an input field that actually doesn't need to be one because of an auto fill generator that generates errors onEnter. Thought this'd be a quick fix for now but obviously not.

Thanks.

Try using a div instead of the span or using the CSS display: block; or display: inline-block;—span is by default an inline element which cannot take width and height properties.

Span takes width and height only when we make it block element.

span {display:block;}

There are now multiple ways to mimic this same effect but further tailor the properties based on the use case. As stated above, this works:

.product__specfield_8_arrow { display: inline-block } 

but also

.product__specfield_8_arrow { display: inline-flex } // flex container will be inline
.product__specfield_8_arrow { display: inline-grid } // grid container will be inline
.product__specfield_8_arrow { display: inline-table } // table will be inline-level table

This JSFiddle shows how similar these display properties are in this case.

For a relevant discussion please see this SO post.

span {display:block;} also adds a line-break.

To avoid that, use span {display:inline-block;} and then you can add width and height to the inline element, and you can align it within the block as well:

span {
        display:inline-block;
        width: 5em;
        font-weight: normal;
        text-align: center
     }

Span starts out as an inline element. You can change its display attribute to block, for instance, and its height/width attributes will start to take effect.

Inspired from @Hamed, I added the following and it worked for me:

display: inline-block; overflow: hidden; 

spans are by default displayed inline, which means they don't have a height and width.

Try adding a display: block to your span.

As per comment from @Paul, If display: block is specified, span stops to be an inline element and an element after it appears on next line.

I came here to find solution to my span height problem and I got a solution of my own

Adding overflow:hidden; and keeing it inline will solve the problem just tested in IE8 Quirks mode
