Downside of "display: block" for images? - css

Is there any downside to converting img from inline-block elements into block objects with the display: block CSS property?
Most of the time, I want them to be block elements. Any useful inline aspects that I am losing? (Perhaps I am not seeing some as useful?)
Should all images be converted into block elements by default? Why are they inline-block elements according to spec?
P.S. I am asking this with considerations for layout via positioning & floats, and surrounding elements.

Well considering that a block will force anything after to line break, there is only one scenario where it would be bad:
If you plan to have another inline element (text, another image, span, etc) beside it

There is one downside :
If you plan to horizontally center an image applying "text-align:center" to the parent element, you cannot display the image as block or inline-block.

Put img { display: block; } in your CSS and forget about it. In the extremely rare instance that you need something different write an exception.

One hack found for block display:"block".
I had this image and the wavesurfer audio wave which I wanted as inline.
But, the display:"block"; in the js of wavesurfer was not allowing it.
What I did was, saved this cdn file locally and changed the display to inline and position to absolute which solved my issue. The change is supposed to be done where the wave element is created.
Hope this helps someone. Thanku wavesurfer creators for such an amazing js.

Transfer block in table-cell on a new line

I’m writing a template for marking on flex/box. And faced with the problem of emulation of some properties. At the moment, I decide them on JS. What complicates code.
So I decided to try to use the property of table-cell for child elements whose parent has the property display: block. Yes, it’s not right, but it works!
When I’m trying to break the table-cell elements to strings, I ran into a problem. And that’s how I tried to solve them:
If the child blocks table-cell overflow the parent horizontally, then
the following blocks are not transferred to the new line. And it is
logical. Example: Nowrap in link.
If I use the cancel flow, I lose equal to the width of columns for the element to be wrapped to the next line. So, this method only works for IE9+. I’m willing to drop IE7, but not ready to abandon IE8. Example: Wrap nth-of-type in link.
If I use the blocks which separate the table-cell on the line, everything becomes fine! But this complicates the CSS and JS code. Example: Wrap with break elements in link.
Example: http://codepen.io/anon/pen/GmgXmO
What ways to break table-cell can be applied, besides the above described options?
An example of a 12 column layout, fix the problem of calculation of the width percentage: http://codepen.io/anon/pen/PmwRvK
In order to make it clear why I do this.
I will be glad to hear your answers! And excuse me for my bad English.
P.S.: Ignore the strange size of the width in percent. It is calculated
according to the formula:
(100 * element.clientWidth / element.offsetWidth).
The smaller size, so it is more. Funny. This rule is applicable only to
the parent display: block containing the child elements display: table-cell

Emulating display block behaviour

I have HTML like below and all is displaying grand, the problem is that due to a problem with Sharepoint 2013's editor your unable to edit the link text but as soon as I remove display: block I can edit the link text, the same happens using float.
My question is there a way to emulate the affect of display: block where it will span the whole width that is available to it without using display or float?
<div class="button">
Link Text
</div>
There is one option to make an inline element to be like a block by using position:absolute without using display or float.
But I hope absolute positioning doesn't fit your want. Thus, the final conclusion is that you must use display or float property to render it correctly.
If you even use absolute then don't forget to keep position:relative to your parent element from which you want to be the element as absolute.
You could try display: inline-block; width: 100%;. You might need to alter the width to take into account any padding or border you've set.
(In the past I've used an edit mode panel and other tricks, so these hacky styles only apply when the page is being edited.)
SharePoint 2013's editor is so utterly awesome isn't it? :-(

CSS: width of a <a>

I'm trying to do something pretty simple: an <a> tag with a background image. The code is found here, http://jsfiddle.net/QWatA/
The problem is that for some reason I can't set the width of the <a> tag in this code. If I had just a normal background and set it with a width it works fine. However seems like if I do it this way I have no control over the width. Ideally I want all the links to have highlights of the same width.
The reason I'm doing this is that I want a different background image for each of the links, so I'm forced to define all those a.class1, a.class2 stuff.
Thanks!!
Add display:inline-block; to your 'a' elements. By default 'a' is display:inline and so does not establish box with width/height.
http://jsfiddle.net/QWatA/1/
yea c-smile beat me to it just put display: block in your css, however if your going to do a.class1, a.class2 and so on with new pictures put it in your ul li a instead of in the a.class1 a.class2 and so on then you only have to write the code once.

css - remove background from link when parent of image

I give my links a background color to make it stand out, the problem is that it will also apply to links which have images as child instead of text. The result is that the image has a small background at the bottom. (see: http://blog.cmstutorials.org/reviews/general/featured-tutorial-of-the-week-05-feb-2011 )
How do i removed the background of links when it has an img as a child? I though that someting like this would work:
.featured_tutorial img < a
CSS does not support a parent selector.
You have to use classes like a.this_link_contanis_img{ /*override background*/ }
Or maybe you could set a new property to the img. This could hide the link's background.
.featured_tutorial img{ /*override background*/ }
Edit: Ok, that wont work in your case..
Cascading Style Sheets don't allow accessing elements "backwards". You can only access children of an element, not its parents.
It has background leaking at the bottom because images are inline level elements by default and are positioned at the baseline of the text line they are placed on thus there is gap between baseline and descent line that gets the color leak. You can get rid of it in two ways. Set css for:
a img { display: block; }
or if you want the to stay displayed as inline
a img { vertical-align: bottom }
this should fix your problem as it will align the image to the descent line of the text line the image is placed on when in inline mode.
Hope it helps,
T.
As mentioned there is no CSS fix but as you're already using jQuery this is the only way i can think of doing it
http://jsfiddle.net/vrqCV/
jQuery(document).ready(function() {
jQuery("a:not(:has(img))").addClass("bg");
});
As has already been pointed out, CSS doesn't have a way of looking "up" the DOM tree. It basically comes down to performance considerations. (Here's one explanation.)
But if you're not averse to the sometimes necessary evil of tacking this sort of thing on with Javascript, jQuery has a :parent selector.

CSS margin problem

I am new to CSS, so please bear with me. I have this form which I'm trying to style. Everything works fine, except the confirmation label which is in a div. I want some space to be there between div.field, and while this works for all the input elements, it doesn't work for the label message which is at the bottom. I tried increasing margin-top, but to no avail. I would like that element to be positioned in the center.
Using the web-developer addon of Firefox, it shows me that the width and height of div.field of label tag specifically is 284px and 209px respectively. Why is this so, when I haven't set it that way?
You can view the code live at jsfiddle: http://www.jsfiddle.net/yMHJY/
The solution is simple, really. Add a margin-top to the parent of the label element, and add overflow: hidden to the div#contact div .field selector.
However, can I just say that the code can be rewritten for much better efficiency and semantic correctness. For instance, I would contain the last massage in a p tag and not a label in a div. Also, I would have each input element placed in an unordered list ul instead of divs. You also have a lot of unnecessary floats and the br at the end of each input is wholly uneeded. Oh, and unless you are embedding Calluna somehow, don't use it - stick to web safe fonts (and if you are, you still need to suggest an alternative, in the user's browser does not support it, and also to give the browser something to display while the font loads).
Edit
Fixed the load for ya, I should be paid for this kind of stuff :) Just stick to better HTML and CSS next time.
http://www.jsfiddle.net/SNrtA/
To center you could add a parent container
<div id="parent">
<label id="label">Your Message Has Been Sent</label>
</div>
div#parent {
text-align:center;
}
or add an id to your original parent div to target it with above css
with regards to the margin, you seem to have an issue with a float:left being set in the
div#contact div input[type=text] class. You need to clear this as it could be causing you margin problems. Try removing this and amending your styles. Why are you floating the inputs left?
