Bootstrap Carousel Full Screen


Answer :

Update Bootstrap 4

Bootstrap 4 has utility classes that make it easier to create a full screen carousel. For example, use the min-vh-100 class on the carousel-item content...

<div class="carousel slide" data-ride="carousel">       <div class="carousel-inner bg-info" role="listbox">             <div class="carousel-item active">                 <div class="d-flex align-items-center justify-content-center min-vh-100">                     <h1 class="display-1">ONE</h1>                 </div>             </div>       </div> </div>

This works to make the carousel items full screen, but carousel items that contain images or videos that have a specific size & aspect ratio require further consideration.

Since the viewport h/w ratio is likely to be different than the image or video h/w ratio, usually background images or object-fit are commonly used to size images and videos to "full screen". For videos, use the Bootstrap responsive embed classes as needed for the video ratio (21:9, 19:9, etc...).

Original answer (Bootstrap 3)

Make sure the img inside the carousel item is set to height and width 100%. You also have to make sure the carousel and any of the .item containers (html,body) are 100%...

html,body{height:100%;} .carousel,.item,.active{height:100%;} .carousel-inner{height:100%;}

Boostrap 3 Full Screen Carousel Demo

Here's an example for Bootstrap 3.x: http://www.codeply.com/go/2tVXo3mAtV


This is how I did it. This makes the images in the slideshow take up the full screen if it´s aspect ratio allows it, othervice it scales down.

.carousel {     height: 100vh;     width: 100%;     overflow:hidden; } .carousel .carousel-inner {     height:100%;     }

To allways get a full screen slideshow, no matter screen aspect ratio, you can also use object-fit: (doesn´t work in IE or Edge)

.carousel .carousel-inner img {     display:block;     object-fit: cover; }

I found an answer on the startbootstrap.com. Try this code:

CSS

html, body {     height: 100%; }  .carousel, .item, .active {     height: 100%; }   .carousel-inner {     height: 100%; }  /* Background images are set within the HTML using inline CSS, not here */  .fill {     width: 100%;     height: 100%;     background-position: center;     -webkit-background-size: cover;     -moz-background-size: cover;     background-size: cover;     -o-background-size: cover; }  footer {     margin: 50px 0; }

HTML

   <div class="carousel-inner">         <div class="item active">             <!-- Set the first background image using inline CSS below. -->             <div class="fill" style="background-image:url('http://placehold.it/1900x1080&text=Slide One');"></div>             <div class="carousel-caption">                 <h2>Caption 1</h2>             </div>         </div>         <div class="item">             <!-- Set the second background image using inline CSS below. -->             <div class="fill" style="background-image:url('http://placehold.it/1900x1080&text=Slide Two');"></div>             <div class="carousel-caption">                 <h2>Caption 2</h2>             </div>         </div>         <div class="item">             <!-- Set the third background image using inline CSS below. -->             <div class="fill" style="background-image:url('http://placehold.it/1900x1080&text=Slide Three');"></div>             <div class="carousel-caption">                 <h2>Caption 3</h2>             </div>         </div>     </div>

Chemistry - Bond Angles In NH3 And NCl3

Answer : Solution 1: As Tan Yong Boon stated, it is Bent’s Rule with which we can explain the lower bond angle of \ce N F 3 \ce{NF3} \ce NF 3 when compared to \ce N H 3 \ce{NH3} \ce N H 3 . The rule as stated by Henry Bent: Atomic s character concentrates in orbitals directed towards electropositive substituents. Fluorine is more electronegative that hydrogen, and the \ce N − F \ce{N−F} \ce N − F bond would have greater p character than the \ce N − H \ce{N−H} \ce N − H bond. And more s character leads to large bond angles. Thus, the bond angle is greater in \ce N H 3 \ce{NH3} \ce N H 3 than in \ce N F 3 \ce{NF3} \ce NF 3 . Now, consider \ce N C l 3 \ce{NCl3} \ce NCl 3 . Clearly, \ce C l \ce{Cl} \ce Cl atom islarger in size than the central atom, nitrogen. Hence the higher bond angle here is due to the steric crowding caused by \ce C l \ce{Cl} \ce Cl atoms.(More pronounced than the electrongativity of \ce C l \ce{Cl} \ce Cl atom). They repel eachother and hence b...

Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Answer : VACUUM is only needed on updated or deleted rows in non-temporary tables. Obviously you're doing lots of INSERTs but it's not obvious from the description that you're also doing lots of UPDATEs or DELETEs. These operations can be tracked with the pg_stat_all_tables view, specifically the n_tup_upd and n_tup_del columns. Also, even more to the point, there is a n_dead_tup column that tells, per table, how much rows need to be vacuumed. (see Monitoring statistics in the doc for functions and views related to statistics gathering). A possible strategy in your case would be to suppress the scheduled VACUUM, keeping an eye on this view and checking on which tables the n_dead_tup is going up significantly. Then apply the aggressive VACUUM to these tables only. This will be a win if there are large tables whose rows never get deleted nor updated and the aggressive VACUUM is really necessary only on smaller tables. But keep running the ANALYZE for the optimiz...

Change The Font Size Of Visual Studio Solution Explorer

Answer : Go to Tools->Options->Environment->Fonts and Colors In "Show Settings for" chose "Environment Font" In "Font" replace Automatic to for example, Arial and change size.
