How do you create a hidden div that doesn't cr

问题:

I want to have a hidden checkbox that doesn't take up any space on the screen.

If I have this:

<div id="divCheckbox" style="visibility: hidden">

I don't see the checkbox, but it still creates a new line.

If I have this:

<div id="divCheckbox" style="visibility: hidden; display:inline;">

it no longer creates a new line, but it takes up horizontal space on the screen.

Is there a way to have a hidden div that takes up no room (vertical or horizontal?

回答1:

Use display:none;

<div id="divCheckbox" style="display: none;">

• visibility: hidden hides the element, but it still takes up space in the layout.

• display: none removes the element completely from the document, it doesn't take up any space.

Since the release of HTML5 one can now simply do:

<div hidden>This div is hidden</div>

Note: This is not supported by some old browsers, most notably IE < 11.

Use style="display: none;". Also, you probably don't need to have the DIV, just setting the style to display: none on the checkbox would probably be sufficient.

In addition to CMS´ answer you may want to consider putting the style in an external stylesheet and assign the style to the id, like this:

#divCheckbox {
display: none;
}

Since you should focus on usability and generalities in CSS, rather than use an id to point to a specific layout element (which results in huge or multiple css files) you should probably instead use a true class in your linked .css file:

.hidden {
visibility: hidden;
display: none;
}

or for the minimalist:

.hidden {
display: none;
}

Now you can simply apply it via:

<div class="hidden"> content </div>

Consider using <span> to isolate small segments of markup to be styled without breaking up layout. This would seem to be more idiomatic than trying to force a <div> not to display itself--if in fact the checkbox itself cannot be styled in the way you want.

Show / hide by mouse click:

<script language="javascript">

    function toggle() {

        var ele = document.getElementById("toggleText");
        var text = document.getElementById("displayText");

        if (ele.style.display == "block") {

            ele.style.display = "none";
            text.innerHTML = "show";
        }
        else {

            ele.style.display = "block";
            text.innerHTML = "hide";
        }
    }
</script>

<a id="displayText" href="javascript:toggle();">show</a> <== click Here

<div id="toggleText" style="display: none"><h1>peek-a-boo</h1></div>

To prevent the checkbox from taking up any space without actually removing it from the DOM, use hidden.

<div hidden id="divCheckbox">

To prevent the checkbox from taking up any space and also removing it from the DOM, use display: none.

<div id="divCheckbox" style="display:none">

If you want to hide the element visually only, but keep it in the html, you can use:

<div style='visibility: hidden; overflow:hidden; height: 0; width: 0;'>
  [content]
</div>

Or

<div style='visibility: hidden; overflow:hidden; position: absolute;'>
  [content]
</div>

display: none will remove the element completely from the html, so it may break some functionalities if you need to access something inside the hidden element.
