Scaling the content of an <iframe> element may be needed if you want to display an object in the area not matching its original size.</p> <p>Below, we are going to show how to scale the content of an <iframe> step by step.</p> <p>Let’s start with HTML.</p> <h2 id="create-html-1">Create HTML</h2> <ul> <li>Create a <div> element with an <span>id</span> "wrap".</li> <li>Place an <iframe> element with an id "scaled-frame" inside the <div>.</li> <li>Add the <span>src</span> attribute with the content you want to display.</li> </ul> <span><<span>div</span> <span>id</span>=<span>"wrap"</span>></span> <span><<span>iframe</span> <span>id</span>=<span>"scaled-frame"</span> <span>src</span>=<span>"/tool/"</span>></span><span></<span>iframe</span>></span> <span></<span>div</span>></span> <h2 id="add-css-3">Add CSS</h2> <ul> <li>Use the width, height, padding, and overflow properties to set the dimensions for the "wrap".</li> <li>Use the width, height, and border properties to set the dimensions for the “scaled-frame”.</li> <li>Add the zoom property to scale the content to 75%.</li> <li>Use the transform and transform-origin properties.</li> </ul> <span>#wrap</span> { <span>width</span>: <span>750px</span>; <span>height</span>: <span>1500px</span>; <span>padding</span>: <span>0</span>; <span>overflow</span>: hidden; } <span>#scaled-frame</span> { <span>width</span>: <span>1000px</span>; <span>height</span>: <span>2000px</span>; <span>border</span>: <span>0px</span>; } <span>#scaled-frame</span> { zoom: <span>0.75</span>; -moz-<span>transform</span>: <span>scale</span>(<span>0.75</span>); -moz-<span>transform-origin</span>: <span>0</span> <span>0</span>; -o-<span>transform</span>: <span>scale</span>(<span>0.75</span>); -o-<span>transform-origin</span>: <span>0</span> <span>0</span>; -webkit-<span>transform</span>: <span>scale</span>(<span>0.75</span>); -webkit-<span>transform-origin</span>: <span>0</span> <span>0</span>; } <span>@media</span> screen <span>and</span> (<span>-webkit-min-device-pixel-ratio</span>:<span>0</span>) { <span>#scaled-frame</span> { zoom: <span>1</span>; } } <p>Here is the result of our code.</p> <h3 id="example-of-scaling-the-content-of-the-and-lt-iframe-and-gt-element-5">Example of scaling the content of the <iframe> element:</h3> <span><!DOCTYPE <span>html</span>></span> <span><<span>html</span>></span> <span><<span>head</span>></span> <span><<span>title</span>></span>Title of the document<span></<span>title</span>></span> <span><<span>style</span>></span><span> <span>#wrap</span> { <span>width</span>: <span>750px</span>; <span>height</span>: <span>1500px</span>; <span>padding</span>: <span>0</span>; <span>overflow</span>: hidden; } <span>#scaled-frame</span> { <span>width</span>: <span>1000px</span>; <span>height</span>: <span>2000px</span>; <span>border</span>: <span>0px</span>; } <span>#scaled-frame</span> { zoom: <span>0.75</span>; -moz-<span>transform</span>: <span>scale</span>(<span>0.75</span>); -moz-<span>transform-origin</span>: <span>0</span> <span>0</span>; -o-<span>transform</span>: <span>scale</span>(<span>0.75</span>); -o-<span>transform-origin</span>: <span>0</span> <span>0</span>; -webkit-<span>transform</span>: <span>scale</span>(<span>0.75</span>); -webkit-<span>transform-origin</span>: <span>0</span> <span>0</span>; } <span>@media</span> screen <span>and</span> (<span>-webkit-min-device-pixel-ratio</span>:<span>0</span>) { <span>#scaled-frame</span> { zoom: <span>1</span>; } } </span><span></<span>style</span>></span> <span></<span>head</span>></span> <span><<span>body</span>></span> <span><<span>div</span> <span>id</span>=<span>"wrap"</span>></span> <span><<span>iframe</span> <span>id</span>=<span>"scaled-frame"</span> <span>src</span>=<span>"/tool/"</span>></span><span></<span>iframe</span>></span> <span></<span>div</span>></span> <span></<span>body</span>></span> <span></<span>html</span>></span> Try it Yourself » <p>In the example mentioned above, we scaled the <iframe> that is 1000px wide down to 750px. If you want to scale the content to 75%, 1000px x 2000px will become 750px x 1500px. We also used prefixes with the transform and transform-origin properties for maximum browser compatibility.</p> <p>Also note that if the @media screen and (-webkit-min-device-pixel-ratio:0) is not defined, the <iframe> will be scaled twice in Chrome. </p> <p>Let’s see another example.</p> <h3>Example of scaling the content of the <iframe> element using internal CSS: <span><!DOCTYPE <span>html</span>></span> <span><<span>html</span>></span> <span><<span>head</span>></span> <span><<span>title</span>></span>Title of the document<span></<span>title</span>></span> <span><<span>style</span>></span><span> <span>#target</span> { <span>width</span>: <span>400px</span>; <span>height</span>: <span>300px</span>; <span>overflow-y</span>: auto; <span>overflow-x</span>: auto; <span>resize</span>: both; <span>position</span>: relative; <span>z-index</span>: <span>2</span>; } <span>iframe</span> { <span>width</span>: <span>100%</span>; <span>height</span>: <span>100%</span>; <span>border</span>: none; } </span><span></<span>style</span>></span> <span></<span>head</span>></span> <span><<span>body</span>></span> <span><<span>div</span> <span>id</span>=<span>"target"</span>></span> <span><<span>iframe</span> <span>src</span>=<span>"/quiz/"</span>></span><span></<span>iframe</span>></span> <span></<span>div</span>></span> <span></<span>body</span>></span> <span></<span>html</span>></span> Try it Yourself » <p>Here, we used an internal style sheet where the overflow property controls the content that doesn’t fit into an area.</p> <p>In our last example, JavaScript is used. We use the contentWindow property to adjust the height of the <iframe> according to the contents. Note that scrollbars do not appear.</p> <h3 id="example-of-scaling-the-content-of-the-and-lt-iframe-and-gt-element-using-javascript-9">Example of scaling the content of the <iframe> element using JavaScript:</h3> <span><!DOCTYPE <span>html</span>></span> <span><<span>html</span>></span> <span><<span>head</span>></span> <span><<span>title</span>></span>Title of the document<span></<span>title</span>></span> <span><<span>style</span>></span><span> <span>body</span> { <span>background-color</span>: <span>#ffffff</span>; } <span>div</span> { <span>width</span>: <span>50%</span>; } </span><span></<span>style</span>></span> <span></<span>head</span>></span> <span><<span>body</span>></span> <span><<span>iframe</span> <span>src</span>=<span>"/snippets/css.html"</span> <span>id</span>=<span>"target"</span>></span><span></<span>iframe</span>></span> <span><<span>script</span>></span><span> <span>var</span> div = <span>document</span>.<span>getElementById</span>(<span>"target"</span>); div.<span>onload</span> = <span>function</span>() { div.<span>style</span>.<span>height</span> = div.<span>contentWindow</span>.<span>document</span>.<span>body</span>.<span>scrollHeight</span> + <span>'px'</span>; } </span><span></<span>script</span>></span> <span></<span>body</span>></span> <span></<span>html</span>></span> Try it Yourself » </div> <div style="padding: 20px; background: #eaf0ff;"> <p>Từ khóa » <a target="_blank" href="https://truyenhinhcapsongthu.net/top/html-iframe-resize-content/6xomfrIe">Html Iframe Resize Content </a></p> <ul style="padding-left: 0"> <li> <h3><a href="https://truyenhinhcapsongthu.net/top/resize-external-website-content-to-fit-iframe-width-stack/Ylxki3ILIk9q1nv" class="relatedtit" rel="bookmark" title="Resize External Website Content To Fit IFrame Width -
