html - Height and weight attributes being ignored by css -

we updates our sites design, can't figure out why css ignoring height , width?

for instance, youtube embedded videos don't stay @ 625x352

<iframe width="625" height="352" src="https://www.youtube.com/embed/jpcfaqiyui4" frameborder="0" allowfullscreen></iframe>

and images original width of 155px , height of 250px don't transform 155x180 specified in html.

<a href="http://my.jpg" target="_blank"><img src="http://thumbnail.jpg"  width="155" height="180" /></a>

anybody has idea how fix this?

for player remove width 100%

iframe {   /* width: 100%; */   min-width: 0;   max-width: 100%; }

or can add inline css "width: initial;" iframe if can not play stylesheet

<iframe width="625" height="352" width: initial;"> </iframe>
