Adding padding to select options

问题

I want to add some kind of space(padding, margin or whatever) between select options in html using css. I've already tried using something like:

 select option {
     padding:10px
 }

however it didn't work. I've already read that this is possible to do but it does not work in IE. Anyway, i'd like to have this to work in other browsers even if it doesn't work in IE.

PS: currently using Chrome

回答1:

styling to select option is very much limited as to maintain a coherence and consistency among all the application in the operating system thus the browser are ought to restrict the style of some basic elements like in your case option tag.

The restriction depends browser to browser, like padding and even margin of option tag works in the mozilla firefox while it doesn't works with chrome.

If it is very much necessary in you website to style the option tag then I suggest you to use some jQuery plugin (you can also make a drop down of your own, its simple).

回答2:

The appearance of option tags is determined by the browser in my experience and often for good reason - think about how differently the appearance is on iOS v chrome and the benefits of this.

You can exert some control of the select element however, by using the browser prefixed appearance attribute.

For example:

select {
    padding: 2px 10px;
    border: 1px solid #979997;

    -webkit-appearance: none;
    -moz-appearance: none;
    -ms-appearance: none;
    -o-appearance: none;
    appearance: none;

    -webkit-border-radius: 4px;
    -moz-border-radius: 4px;
    -ms-border-radius: 4px;
    -o-border-radius: 4px;
    border-radius: 4px;
}

However when clicked, they appear as they normally do in whatever browser you're using.

If you want finer control, your best bet I think is @sumitb.mdi's suggestion of a jquery plugin or build something similar yourself from scratch.
