How to style the first occurrence of an element inside of another element?

by in , 0

Here's my problem.
<div id="content">
    <p>First paragraph that needs to be yellow.</p>
    <p>Second paragraph that need not change. :) </p>
    <p>Third paragraph that need not change. :) </p>
If I use #content p:first-child {color:yellow; } it doesn't work because p isn't the first-child of content... h1 is the first born.
How can I do this without touching the HTML code?

Htaccess show no_found picture if picture is not exist

RewriteEngine On
RewriteCond %{REQUEST_URI} \.(jpg|jpeg|gif|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .*$ /no_picture.png [L]
Let's break it down as to what each line means.
RewriteCond %{REQUEST_URI} \.(jpg|jpeg|gif|png)$ [NC]
Check to see if the requested file is of a file extension in the parentheses (). In this case, we're testing to see if the file name ends in either .jpg, .jpeg, .gif or .png
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
Check that the file is not there and it's also not a directory.
RewriteRule .*$ /no_picture.png [L]
If a requested resource/file passes all those tests, then it's an image that does not exist. So serve back the image of no_picture.png to the browser. This will keep the filename. If you want to redirect to the no_picture.png filename, change [L] to [R]

document.getElementById('mytextarea').innerHTML = str.replace(/<br\s*[\/]?>/gi, "\n");
or using jQuery:
var str = $("#mydiv").html();
var regex = /<br\s*[\/]?>/gi;
$("#mydiv").html(str.replace(regex, "\n"));
edit: added i flag
edit2: you can use /<br[^>]*>/gi wich will match anything between the br and slash if you have for example <br />
