What to change in order for this to shrink? - javascript

So I wanted to make a website which is pc related. I was into coding a few years ago, and I decided to pick it up again. I came across the following problem.

If you look at this picture, you can see the part of the site which I made.
I want it to be responsive so that the text on the left side of the picture (explanation of CPU) is shrinking when I shrink my browser.
However, this is happening:

I want this text which is beneath the picture, to be next to it and shrinking. After a few hours trying things with display: and margin: etc, I decided to ask you guys.
Here are my codes (I know the codes aren't the best):
CSS: https://imgur.com/UOThxjv
HTML: https://imgur.com/DAhC6dx
if you need any clarification, please ask me.

You need to set divs around h4 dynamic width to something like 60%. Make div container for img and set its width to 40%. You should use parahraphs instead of heading-4 for text as well.
Modify HTML:
<div class="text">
<p>your text</p>
</div>
<div class="img-div"><img src="pc.png" alt="pc.png" /></div>
CSS:
.text {
width: 60%;
float: left;
}
.img-div {
float: right;
width: 40%;
}
.img-div img {
width: 100%;
height: 100%;
}
Responsive image map
To make the image map responsive you need to use a js script to manipulate coordinates on window resizing or use .SVG images for image map:
Check out this SO question.
JS image map resizer script

All the dimensions and margins in your CSS code are constant pixel lengths.
Instead, you should make them percentages of the window size. For example, you could make the width of a div tag or an image always be 20% of the screen size by putting in this line of CSS to its CSS class as shown below:
width: 20%;

PDF Type view using html and css. Page overflow problem

I am trying to create a "document viewer" of sorts using html and css. I'm wanting the end result to look somewhat of a pdf when viewed in an iframe with no border.
I have a parent div setup with a class of paper. This has some box shadow and other styles attached to it.
<div class="paper">
</div>
Within this I have children divs setup with a class of page. This is where all the content sits for the page.
<div class="page">
</div>
My problem is when the content gets too long for a page and you scroll to the next "page" it all mixes together and looks like junk. I have attached a code pen to further assist in being able to visually see what I am struggling with.

You can change your page class in CSS with this:
.page {
height: 100%;
margin-bottom: 15px;
padding: 20px;
display: table;
text-align: center;
}
What is the problem?
If the content in your pages gets too long, it overflows the height end kind of "bleeds" on the next page.
What to do?
You should set a fixed height of 100vh to your paper
Then, tell it not to expand with: overflow: scroll
Use min-height to set the height of your page, instead of height: it will naturally expand the height of the pages instead as you content grows
Finally, just in case, set overflow: hidden to page

Bootstrap / Css - 2 DIV same height

I've got HTML+CSS code. I need 1st div (row-1, white colored) to take first half of the container height, and 2nd div (row-2, orange-colored) to take the second part.
Here is my html:
http://pastebin.com/ipiEKHBZ
and my css:
http://pastebin.com/jtxw695F
Revised answer: After realising the default approach did not work with your HTML, this should work. You have classes .content-row-1 and 2 respectively. You can use those to tell the corresponding rows to always use a certain portion of the height. For this to work you also need to manually fix the positioning. (Someone correct me if this can be done more elegantly) For example those classes could look something like:
.content-row-1 {
background: #eee;
position: absolute;
top: 10%;
display: block;
height: 40%;
width: 100%;
}
I noticed that your footer already takes 10% of the height and and assumed you did not want any overlap or gaps. For that to work you should also give your header a percentage for height (10% in my example to keep things simple).

How to scroll a large image inside a smaller div using mouse click and drag?

I want to place a large image inside a div and let the user scroll through the image using the mouse (click and drag to the desired direction). How can this effect be achieved?
CSS:
#image{
position: relative;
margin: 0 auto;
width: 600px;
height: 400px;
top: 300px;
background: url("http://www.treasurebeachhotel.com/images/property_assets/treasure/page-bg.jpg") no-repeat;
}
HTML:
<div id="image"></div>
EDIT:
I want to implement this myself in order to gain knowledge, 3rd party frameworks are last resort.
<html>
<body>
<div style="width:200;height:200;overflow:scroll;">
<img src="/home/james/Pictures/scone_ontology.png" />
</div>
</body>
</html>
Check out jQuery UI Draggable. The first example sounds like exactly what you are trying to do:
https://jqueryui.com/draggable/
So you just want 600w 400h div, with a "map" inside that you can scroll around and look at with the mouse? You're very close already.
Have a div with the size you want the end-product to take up. Make sure you set its css to overflow:scroll;. Then put your image inside this div. Your image can ofcourse also be the background-image of a div.
And that's it.
A cool trick would be to wrapp all this up in a div that is slightly smaller, with overflow:hidden. Just small enough to hide ugly scrollbars. But that might be bad usability.

Show part of Image (sub-image in image strip) without squishing it?

I have an image on a webpage. It's a pretty big image, however. It's 6144*768. In actuality, it is a series of 6 images mushed together.
I read that it's better practice to load this one image instead of loading 6 images. I've found this to be true as well, when I used tables and CSS.
However, when I set this image as the source of an image element and then set the size of the image element to 1024*768, the image is squished. Ack!
How can I get this image to be not-squished by using only Javascript? Also, how could I move the background of the image?
[example: Imagine a really long strip of paper. Then, place a small cut-out rectangle of paper over that somewhere on the strip of paper, so that you can only see the part of the strip that is inside the rectangle. This is what I want to do]
Place the image inside a container element, and set the overflow to hidden using CSS.
Leave the image as it is and it won't be squished
HTML
<div id="imgContainer">
<img src="myImage.jpg" alt="" width="6144" height="768" />
</div>
CSS
#imgContainer
{
height: 1024px;
width: 768px;
overflow: hidden;
}
Then to move the image use negative values for the CSS style margin-left.
#imgContainer img
{
margin-left: -1024px;
}
You can do this with jQuery as follows
$("#imgContainer img").css("margin-left", "-1024px")
What OP is looking for is CSS Sprites (also see A List Apart or Smashingmag).
Don't scale your image with CSS; instead, put it in a wrapper div and do something like this in your CSS:
#myImageWrapper {
height: 1024;
width: 768;
overflow: hidden;
}

Is it possible to get an adjustable "view" of a static image in HTML?

I'm working on a web app where I have an image, and, for lack of a better word, a "view" of that image which is a box limiting what you can see to whatever part of the image is inside the box. The view can be adjusted by dragging the edges around, and the image is stays. However, I also want to be able to drag both the view and the image around together.
The best analogy I can think of is the Snipping Tool in Windows that you use to capture a portion of your screen.
I've tried a div with a background image, but that always resizes the image to fit the div. Right now I'm trying to have a div that contains an img, and setting the div to have overflow:hidden, but that makes the image stick to the upper left corner of the div.
Help? Thanks in advance!
Sounds like you want something that masks the image and only shows a segment.
Assuming a structure like.
<div class="img-mask">
<img>
</div>
You can set the styles of the mask to be overflow hidden with a width and a height (this creates the mask). Then position the image relatively, left and top till it's where you want it to be.
.img-mask {
overflow: hidden;
height: 200px;
width: 200px;
}
.img-mask img {
position: relative;
top: -25%;
left: -25%;
}
This should center the image to the mask.
I think there's a CSS property cut out for exactly this task: the clip attribute.
Here's the W3schools tutorial: http://www.w3schools.com/cssref/pr_pos_clip.asp. Click the Try it Yourself button to get a hands-on idea.
With this the CSS property applies only on the image and you do not need an additional masking div.
