jQuery changing style of HTML element

I have a list on HTML

<div id="header" class="row">
    <div id="logo" class="col_12">And the winner is<span>n't...</span></div> 
    <div id="navigation" class="row"> 
        <ul id="pirra">
            <li><a href="#">Why?</a></li>
            <li><a href="#">Synopsis</a></li>
            <li><a href="#">Stills/Photos</a></li>
            <li><a href="#">Videos/clips</a></li>
            <li><a href="#">Quotes</a></li>
            <li><a href="#">Quiz</a></li>
        </ul>
    </div>  

it changes fine to show horizontally on CSS change

div#navigation ul li { 
    display: inline-block;
}

but now I want to do it with jQuery, I use:

$(document).ready(function() {
    console.log('hello');
    $('#navigation ul li').css('display': 'inline-block');
});

but is not working, What do i have wrong to style my element with jQuery?

thanks

Solution 1:

Use this:

$('#navigation ul li').css('display', 'inline-block');

Also, as others have stated, if you want to make multiple css changes at once, that's when you would add the curly braces (for object notation), and it would look something like this (if you wanted to change, say, 'background-color' and 'position' in addition to 'display'):

$('#navigation ul li').css({'display': 'inline-block', 'background-color': '#fff', 'position': 'relative'}); //The specific CSS changes after the first one, are, of course, just examples.

Solution 2:

$('#navigation ul li').css('display', 'inline-block');

not a colon, a comma

Solution 3:

$('#navigation ul li').css({'display' : 'inline-block'});

It seems a typo there ...syntax mistake :))

Solution 4:

you could also specify multiple style values like this

$('#navigation ul li').css({'display': 'inline-block','background-color': '#ff0000', 'color': '#ffffff'});
