Is it possible for a div nested within another div to still occupy space on the page despite being set

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$("select#choosebook").change(function(){
    $(".title").slideDown("medium");
});
</head>

<body>
<div class="booktitle">
    <p>
    <font color="red">*</font>Book:
    <select id="choosebook">
        <option>Choose a Book...</option>
        <option>Add new Book...</option>
    </select>
    <div class="title" style="display:none">**
        <font color="red">*</font>Title: <input type="text">
    </div>
    <font color="red">*</font>Page: <input type="text" class="page">
</div>
</body>
</html>

The issue as described is that the hidden div with the class "title" occupies space even when it is invisible due to being hidden. The goal is to eliminate this space until the JavaScript function slides it down. How can this be achieved on the web page?

Thank you!

EDIT: Here is a screenshot provided showing the problem, where there is unwanted spacing between the Book input and the Title input. Before the 'title' input slides down: After the 'title' input slides down:

Additionally, here is the CSS for reference:

<style type="text/css">
    @import url("layout.css");
    .page {
        width: 50px;
    }
    .URL, .booktitle {
        margin-left: 24px;
        display:none;
    }
    .title {
        display: none;
    }
    .newtag {
        display:none;
    }
    .amount, .addtag {
        width: 100px;
    }
    .details {
        width: 275px;
    }
</style>

Answer №1

The empty space is not caused by the div itself, but by the unnecessary <br> tag immediately following it.

Can we please remove the outdated <font> tags? They are quite painful to look at!

Answer №2

If you're noticing a large gap beneath the Book dropdown, it's likely due to an unclosed p tag in your HTML code. The open p tag is creating a default margin that is causing the extra space. Simply close the p tag and the margin should disappear.

I also recommend always including a doctype declaration in your page, as mentioned in my previous comments on your question.

Answer №3

Using the font element is no longer recommended, please use a span instead. Also, make sure to close your script element properly.

After tidying up the code, it looks like this now:

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$("select#choosebook").change(function(){
    $(".title").slideDown("medium");
});
</script>
</head>

<body>
<div class="booktitle">
    <span style="color:red">*</span>Book:
    <select id="choosebook">
        <option>Choose a Book...</option>
        <option>Add new Book...</option>
    </select>
    <div class="title" style="display:none">
        <span style="color:red">*</span>
        Title: <input type="text" />
    </div>
    <span style="color:red">*</span>
    Page: <input type="text" class="page">
</div>
</body>
</html>
