on this page https://goo.gl/JYeu2z there's a google map in embeded in an iframe.
<iframe style="border: 0;" src="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d52703.72503342482!2d58.663129170303066!3d34.35091546442272!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x3f121fdc66f0de93%3A0x97ae5d04f8abd8f!2sGonabad%2C+Razavi+Khorasan+Province%2C+Iran!5e0!3m2!1sen!2sus!4v1493787455772" width="2000" height="300" frameborder="0" allowfullscreen="allowfullscreen"></iframe>
Eventhough the iframe is set to the width of 2000px, it displays as 700px wide because Wordpress puts it inside P tags, which is set to 700px.
Is there a way to tell browser to ignore that 700px constraint and let the iframe appear at 2000px?
I repeatedly have similar issues when I want to some items to appear edge to edge but WP automatically puts them inside P tags so they appear only 700px.
Is there a magic solution to this predicament?
I responded three days ago. Apply the fix I gave you to the relevant html and css. I don't use WP, so cannot give you specifics on procedure. Are there not WP support forums you can query?
