'how give line-height to an img's alt text in CSS

i have given to all my img alt text a specific font-size, so that they can be more readable if the img doesn't get loaded. But still the line-height is still too much. i tried to decrease the line-height in the css code below, but it doesn't effect. i don't want any jQuery work-arounds. I prefere to fix it css only.

thank you.

img[alt]{
    font-size: 8px;
}
css

Try this

<span style="font-size: 1.75em">
            <img alt="Some Text" src="http://www.someimage.com/img/010.jpg">
        </span>

you can use "font-size" attribute to that img tag or you can use img tag in span or div any container tag , it'll work

I've tried this one and it works fine

<span style="font-size: large;"><img alt="your text" src=""></span> 

thanks :)
