When writing a webpage in html, can you use two different quantitative measures for width and min_width?
For example can you use:
width: 90%
min-width: 600px
Do they both have to be the same unit of measurement (px or %) or does it not matter? I'm trying this in a webpage but it is not working. I am using this to minimally size a jqGrid table, but I wouldn't think that would matter.
These can definitely work together. The width declaration will be set 90% of whatever it's container width is. The min-width makes it so that element has to be at least 600px wide.
It should be min-width: 600px;. They can be used together and can use different units. See an example here. The element will not shrink to any smaller than the min-width, if there is enough space it will use the width value, so in this case 90% of the available space.
You don't described exactly how you allow the user to change the grid size. If you use gridResize then you can add additional options like
$("#list").jqGrid('gridResize', {minWidth: 450, minHeight: 100});

Is there any difference between declaring both width and max-width and declaring only one?
As I have understood, using only the max-width property causes all of an element's content to be fit dynamically when the viewport is resized.
Consider the following pen, feel free to resize the window to see what happens:https://codepen.io/harrison-rood/pen/KKzPQMW
The first example is an image with an explicit width of 800px.
The second is an image with a max-width of 800px, but a width of 100%.
See how one is responsive and the other is not? In the first example, we're telling the image it needs to be exactly 800px. In the second example, we're saying that the image should be a fluid 100%, but not any bigger than 800px, no matter what.
You can also use this idea in reverse. The third example has an image with a width of auto (as big as possible) but a max width of 100%, meaning that it will be as big as its container, but not overflow out of it.
The fourth example shows what would happen without max width. See how the image stretches way past its container because it is much larger?
Hope this clears things up! If it does, be sure to leave an upvote!
This is because screen resolutions can be different sizes. Lets say you have an element with a width of 15%, if you increase your window width, 15% becomes larger in pixels. You can set a max-width from preventing it from going over a certain width in pixels.
Using max-width, as the name implies, means that, when a container contains more content than it can fit, its width won't exceed the specified max-width.
max-width is specifically used to prevent a container's width from increasing when it contains more content than it can fit—instead, when max-width is specified, the content will overflow out of the container.
I want my site to stop resizing (stop being responsive and lock at the desired size) after user minimizes it to a certain point lets say 10inch screen in pixels and when u scroll left of right it is not responsive after that point.
I have tried
body {
min-height:30%;
min-width:30%;
}
But nothing happens at all.
percentage
The percentage CSS data type represents a percentage value. It
is often used to define a size as relative to an element's parent
object. Numerous properties can use percentages, such as width,
height, margin, padding, and font-size.
use min-height:30vh instead of min-height:30% same goes for min-width:30vw for min-width:30%. But if you want to use % you then have to set the width and height of the parent element
:root{width: 100vw; height: 100vh}
or
html{width: 100vw; height: 100vh}
you are looking for media query my friend. check this out:
https://www.w3schools.com/css/css_rwd_mediaqueries.asp
you'll use a media query to specify the pixel size (and other options) for example 600px max width is a good measurement for phones. inside the query, you'll write regular CSS to apply under those size conditions.
let me know if you need samples, i'll send you some of my code to help.
here is another good post on stack

I'm building a responsive website and I'm wondering what unit I should use? I've seen a lot of sites using pixels (px) for measurements and I've seen some using percent (%). Is there a preferred — or right — way of doing responsive design?
I've found percent to be hard to use, since it makes calculations hard and I've ended up with values like 2.754% and so on when setting widths/margins etc. Pixels seems easier, it's just simple addition and subtraction, but I've read that it isn't "future proof" or something like that and wont scale properly if the user zooms in the browser window. Is that still true?
If you have any experience or expertise, please share! I would love to hear what you guys have to say!
Thanks!
For layout type things like the sizes of boxes, you want to use % because you will typically have several columns sized as a percentage of their parent that will stack on top of each other at a certain breakpoint (width:100%). No other unit will allow you to fill 100% of the space like % does.
For padding/margins use em, normally you will want to space your elements out relative to the size of your text. With em (the with of an 'M' character) you can quite easily say I want approximately 1 character spacing here.
For borders you can use px or em, there is a difference though. If you want your border to look like it's one pixel wide on all devices, use 1px. It may not be one pixel on all devices however, high density displays convert 1px into 2px for example. If you want your border to be a size based on your font, use em.
For fonts use em (or %), the use of em carries through parents to children and it just a nicer unit to work with over px.
Of course you must use percentage. But with the min-height, max-height, min-width, max-width CSS keys.
For the next generation
vw and vh. The vw is 1/100th of the window's width and the vh is 1/100th of the window's height.
For responsiveness they are going to be the new units.
Use percentages along with min-width and max-width in pixels. This stops percentages making your divs too small or too large. eg
div {
width:100%; //full width of browser
max-width: 960px; //this means it will be 100% of the browser until 960px then it will stop expanding
}
For layouts vh and vw are good because they are relative to the device's view port. They give you the possibility of designing with the view port of the device in mind. With this said you know what will show on the window and what won't without being too careful.
For text em is best because if it's responsive features.
What's the basic difference between [width and height] and max/min[width and height] and where should we use each of them?
Thanks in advance........
The basic difference is that width and height will specify the exact width and height of an object. Max/min width and height will specify the maximum or minimum height and width that an object needs to be.
Say you had a div that you wanted to load images into, but you wanted all images to be the no larger and no smaller then a specific width or height, then using min/max calls would be ideal.
In other cases, where you know the width and height (say for only a specific image) then you do not need max or min height/width calls.
It is also important to note that max/min height and width calls will over-ride height and width calls.
Here is some more information:
CSS Height and Width
CSS Tests - Min and Max
width/height give you the strict constraints. max-height/max-width tell your element to be not wider/higher than a certain value, but the element can still be smaller than that value.
max-height/width are commonly used when you want to make the site behave according to the screen it is viewed on, but to not be super huge on the large screens anyway. The same about the elements - you might want to accept images of any size, but want to make sure they are not breaking your site layout. Hence you use max-width/height.
They don't work in IE6 though. If you need to support min-width/height in IE6 you can use regular width/height. IE6 will treat them as minimum values anyway and will expand them in case content needs more space. Both min/max width/height work fine in IE7+
I am using Yahoo's UI Grids to structure most of my pages. One of my pages is a Google map and I need about a 400 pixel fixed left column to put map legend information into. YUI Grids however only offers 3 columns for their 100% page layouts, namely 160px, 180px and 300px.
Is there a way that I can customize their 'template 3' which provides the 300px column to get my 400px column I need?
I've determined how to do this. Kudos for Nate in the YUI forums for pointing me in the right direction.
To set a fixed left column, you need to divide the column pixel width by 13 to determine the em's for all non-IE browser's. For IE, divide the column width by 13.3333
e.g. wanting a fixed 480px width, 480/13 gives me 36.9231em for non-IE and 480/13.33 is exactly 36em for IE
Using template 3, the CSS is:
.yui-t3 .yui-b {
float: left;
width: 12.3207em; *width: 12.0106em;
}
.yui-t3 #yui-main .yui-b {
margin-left: 36.9231em; *margin-left: 36em;
}
Also, if you want to tweak margin's e.g. zero margin, you can do something like:
#doc3 {
margin: auto 0;
}
Grids is presently deprecated in YUI 3 - a bit of a shock when I saw that. There will be some browser(s) that drop off the A category in July and as a result, Grids will be reworked given that some of the initial design decisions were based on older browsers of course.
There is definitely a way. I think its just a matter of tweaking the CSS to either add in another 400px column, or modifying an existing column to fit your needs. If you are adding another column, be sure to account for the additional width (plus margin) and either reduce width on other elements, or increase the width of your containing element.
If the layout is using 100% width of the browser, width may not be an issue, but if your content is wrapped in a container element which holds all of your columns, be sure to adjust the existing elements to make up for the size of your new column.
EDIT: Also if you are dealing with 100% width layouts, its probably better to size your columns using percentage, instead of a fixed pixel size. Since the containing element for your columns will be the user's screen, if you use percentage then the column sizes should adjust relative to their resolution/window size.
If you want your new column to appear on the left of the your other columns, typically you would place it before the other columns in your markup, and apply a "float:left" property. But, take a look at how the other columns are set up in the YUI CSS, and follow their method.
I hope that helps.
