Remove border from IFrame

Solutions for historical browsers

Let's be real, nobody likes to cater to yesteryear browsers like IE6, but sometimes you got to do what you got to do. If your user base still includes these legacy gatecrashers, resort to the frameBorder attribute with a capital "B"—even though it's deprecated. I've seen it works wonders!

<iframe src="example.html" frameBorder="0"></iframe>


Comment: /* Yup. Back in time we go! */

Integrating neatly

Next up on our borderless journey—SEAMLESS integration. Remember, the key is consistency. So, make your IFrame's background color match the parent page. No sneaky mismatched hues, please!

iframe {
    background-color: #ParentPageBgColor; /* Twinsies with the parent page */
}


Prep for the worst-case scenario

You've got to be ready for everything, even for browsers that live under a rock and do not support IFrames. Provide alternative content inside the IFrame tag—think of it as a survival kit:

<iframe src="example.html" frameborder="0" style="border:0;">
    <p>Your browser does not support iframes.</p>
</iframe>


Comment: /* Be prepared! It's the scout's code. */

Customizing the IFrame

To control your IFrame's size, specify width and height. Prevent the scrollbars from showing by adding scrolling="no". Keep those scrollbars where they belong—outside the iframe!

<iframe src="example.html" frameborder="0" scrolling="no" width="300" height="300"></iframe>

Comment: /* Look ma, no scrollbars! */

Top-notch styling practices

Adorning the IFrame in the best attire involves understanding some niftier parts of cross-browser compatibility. Round up your tips and tricks:

Bring in the broom with CSS reset

Sweep away the default styles that naughty browsers might add:

iframe {
    border: 0;
    margin: 0;
    padding: 0;
}


Place the crown with !important

If some pesky style overrules yours, bestow the !important rule:

iframe {
    border: none !important;
}


Mind your surroundings

The culprit could be a border on a parent container:

.parent-container {
    border: none; /* ssssh...who put that there? */
}


Outsmarting uncertainties

When the IFrame border acts up despite all attempts, here are some edge scenarios to consider:

The sneaky CSS style

A conflicting CSS rule might be reintroducing the border. Use developer tools to inspect the IFrame and trace the deceptive style.

The nostalgic browser quirk

Some browsers harbor a soft spot for their older versions and may show a border even when explicitly told not to. Might have to resort to conditional loading of stylesheets.

When Iframe parties with a frameset

Inside a <frameset>, the <iframe> borrows border rules. Wrangle it back with:

<frameset border="0">
    <frame src="example.html">
</frameset>
