I would like to know all the different types of div classes. I have a small amount of understanding of divs.
Here's an example of how I would use a div and then customise the content in the div using CSS.
div .header {
font-family: "Bebas";
font-size: 25;
font-color: #00FF00;
float: right;
position: relative;
right: 120px;
bottom: 1095px;
}
So, if you're not following my question(s), what I want to know is;
A. Does that code look alright?
B. How many div classes are there, and what are they called?
and C. Could someone give me a brief explanation as to what they are and more specifically, how to use them.
I'm mostly self-taught, in case you wondered.
To answer your question you can have as many div as you want. and you assign class or id to identify each div. just be aware id are unique, you can not assign the same id to more than one elements.
and your css format is right, but I am not sure why you declare right/bottom those will only render when your position is absolute with out float.
I would suggest you go through some tutorial at http://www.codecademy.com. it's free. and don't required any sign up, unless you want to save your progress.
As previously said, you can set as many div classes as you'd like, they're not preset. I would also recommend doing the Codecademy tutorials.
Looking at your code, you're telling the div to float: right; - fine. Then you use position: relative; followed by right: and bottom: values. Either float or position, no need to do both.
The way you've written the rule is probably not how you mean it. It's currently looking for this -
<div>
<div class="header">
<p>Content</p>
</div>
</div>
An element with the class header that's inside a div.
You should remove the space so your rule becomes -
div.header {
enter code here
}
Yes, the code you wrote looks fine. I don't know what you intended to do with this code, so going by just the syntax it looks fine.
Coming to your sub-question B and C,
div is block level element with almost no specific task or objective. They are general purpose elements used for most tasks. Block level elements act as containers and div is the most basic type of container we get.
We can use div to store other elements, design web document and proper indention of text and images and what not.
Let's answer your questions one by one:
A - Your code looks fine ( depending on your needs ).
B - You can use as many div classes as you like.
C - Simply you can use div classes to describe it's content like: div.header , div.body , div.footer and so on.
But i recommend to use the new HTML5 semantic tags instead, it is easy, clear and more powerful with search engine optimization.

I'm essentially trying to replicate the webpage output for this assignment. Pictures used in webpage are here. That's basically my ultimate goal in all of this, getting this webpage as close to the Desired Output as possible. Not just similar, but as close to identical as possible.
This needs to be done in a way that doesn't just superficially reflect the intended output, but is done in the "right" way. For example, I could very well just adjust padding and margin sizes until it looks the way it needs to be, but that wouldn't solve the overarching problem and makes for badly styled code.
This has to be predominantly done with CSS. Only organizational HTML tags can be used and no packages or code can be imported.
Problem:
Each review is supposed to be separated by 20pt of vertical distance. This isn't working out for whatever reason.
It might have something to do with the fact that I've got some of my reviews looking like this when I need them to look like this.
That might have to do with the fact that padding is applying only to the text when it needs to apply to the review as a whole.
You can see in the first image that the blue bar, which represents padding, is only under the text and not under the image and the text.
I'm wondering if this has something to do with img elements being inline elements and not block elements? Any advice you have on this would be greatly apprecaited.
Code:
CSS
HTML
The padding does not work with your images because you have
float: left
applied to them. If you take that property out, the padding will take the img into account.
On a side note: maybe you should reconsider your html structure. Logically the review text and the reviewer belong together, so they should be enclosed by some parent div element. Just look at the real rotten tomatoes website and how they structure their reviews and let that "inspire" you ;-)
But basically it should be something like this:
<div class="review">
<div class="review_quote"></div>
<div class="review_source"></div>
</div>
Well structured HTML really helps with styling. HTML and CSS go hand in hand, so if your HTML is messy your CSS will be messy and "hacky" too. So first make sure your HTML makes sense (grouping, nesting, etc.) first.
add this class in your css
.reviewer-text::after {
clear: both;
content: "";
display: block;
}
Well.. your padding in css is refering only to class 'reviewer-info'. Elements with class 'reviewer-text' got their padding set to 8px;
If you want to have result for that block like on the picture apply bottom padding for 'reviewer-text'. Change:
.reviewer-text {
padding: 8px;
}
to:
.reviewer-text {
padding: 8px 8px 20px 8px;
}
See: https://fiddle.jshell.net/a9xxoz8L/1/
I'm creating a site with a horizontal navbar in which the buttons are designed as elements, making them easy to differentiate, and they individually light up when you a:hover over them. Here's a link: http://allpropestmanagement.net/commercial2.html
Obviously not a finished product.
My current problem involves that big purple field on the far right of the navbar, the one that's not a button. That too is an element, but with hover disabled and a whole load of nonbreaking spaces to pad it. That's the problem. I would like that purple field to extend all the way to the right end (with a tiny margin, like it does on the left side). The trouble with nbsp, as you can imagine, is that there's a finite number of them, and they don't scale. So if the navbar is the perfect length on my computer with, say, 16 nbsps, on someone else's machine it won't reach all the way and on yet another person's it will reach too far.
The html looks like this:
<div id="navmenu">
<form>
Home
Commercial
Meet The Pro
Contact
<a id="farright" style="border-top-right-radius:25px;">
<i> "We'll get the job done right!"
</i></a>
</form>
</div>
I feel odd saying this, but the css is kind of bulky and I'm having trouble formatting this post. Perhaps I'll add it in a few minutes once this post is visible, but the css file is "smithmicropurple.css".
Anyway, I would like a way to stretch that element so it always fits correctly, or if not, some other method that achieves the same effect. I have already tried setting widths individually for each element and that doesn't appear to work.
I like to do these types of things to "help" others (rarely, if I'm lucky), but also to help me learn more about html/css.
So I've given it the old college try with this FIDDLE.
HTML
<div class='holderdiv'>
<a href='#'>One</a>
<a href='#'>Two</a>
<a href='#'>Three</a>
<a href='#'>Four</a>
<a href='#'>We'll Get the Job Done Right!</a>
</div>
I won't post the CSS because it's pretty long. It's in the fiddle.
Please don't consider this a "real" answer. Perhaps just something to think about.
Semantically, I am not sure why the parent is a form element, i'd suggest changing that to a HTML5 <nav> element. (assuming you're using HTML5, of course)
The approach taken here is to set the child elements to display:table-cell, and give the targeted element, #farright a width of 100% to fill the remaining space. Also, text-align:center will effectively center all the child elements. No need for %nbsp;
#navmenu {
font-size: 14pt;
margin: 5px 0 0 5px;
}
#navmenu form {
width: 940px;
}
#navmenu form > a {
display: table-cell;
white-space: nowrap;
text-align:center;
}
#navmenu #farright {
width:100%;
}
Lately I'm using a CSS structure that makes HTML much cleaner but I don't know if there's something wrong with this.
Instead of using:
.top { //properties }
.top-wrapper { //properties }
.top-logo { //properties }
And for HTML:
<div class="top">
<div class="top-wrapper">
Logo
</div>
</div>
I'm actually coding like this:
.top { //properties }
.top .wrapper { //properties }
.top .wrapper .logo { //properties }
And for HTML:
<div class="top">
<div class="wrapper">
Logo
</div>
</div>
Is it wrong to do this?
It is not wrong, but the more selectors you have, the higher the resulting specifity of your style. For more information about specifity see http://www.w3.org/TR/CSS21/cascade.html#specificity.
Imagine your example
.top .wrapper .logo { font-size: 10px; }
followed by this:
.logo { font-size: 20px; }
The <a class="logo"> will have a font-size of 10px, even though you specified it to be 20px for the second declaration.
It isn't necessarily "wrong" to do this, it works and if you find it easy to use I'd say go for it!
However - there are some drawbacks to this approach, for example your CSS file will end up larger, which will mean longer download times for anybody viewing the website (granted this effect may be negligible)
There's also the issue that, if you want to re-use the styles of top-wrapper on another element, you have to place that element inside a div with a top class, this ends up cluttering your HTML.
(For more information on the above point see OOCSS)
At the end of the day there are benefits and drawbacks to any approach, if you feel really comfortable with this approach, and it is working for you - then stick with it!
EDIT:
It should also be noted that you're second approach will take longer for the browser to render than you're first approach (the browser has to check multiple conditions instead of just one) for more info see this question
Nope.
What your second code is doing is saying, "target all the elements inside elements that have class top, that have the class wrapper and apply such and such properties"
On the other hand, your first code is only targeting the elements that have the class top-wrapper (or whatever) regardless of their parents class.
Depends how you will use that specified class
.logo { //general properties }
.top .wrapper .logo { //specific propery to top wrapper properties that overrides .logo }
.bottom .wrapper .logo { //specific property to bottom wrapper that overrides .logo }
HTML
<div class="top">
<div class="wrapper>
Logo
</div>
</div>
<div class="bottom">
<div class="wrapper>
Logo
</div>
</div>
Generally, it is better
It's not wrong, but it may get verbose and a little slower if you are have 10 levels of nesting. The result may also be harder to debug if both .logo and .wrapper .logo are styled.
On the other hand it may be nice to have a .button looking different in .content or in .menu. In general, use what makes sense in a specific use case.
No right and wrong here: everything depends on the site you are building, if you are in a team and what makes sense to you.
Personally I don't think the html is any cleaner now than it was previously (in this small example) but your CSS specificity has increased and that could have a detrimental knock on effect.
I now ask myself 'why do I want this element styled in this way?'. Sometimes it's because of inheritance, sometimes because it's a specific case that happens to be in a certain area. The example you use seem a good candidate for inheritance, but looking at the rest of the site might lead to a different conclusion.
Adding longer class names doesn't, to my knowledge, greatly decrease performance. I suspect the only effect would be marginal and is unlikely to be noticeable. Really dependant on the implementation
Additionally if you were 'reading' the html it may make more sense to read have class names like top-logo, other wise you need to look for the appropriate ancestor (bearing in mind there may be more than one that could be applicable).
I'm busy moving toward an OOCSS / BEM method (google these for more, so many resources out there...) myself because I believe it will make maintenance easier in the future, plus I find it makes more sense within a team environment. These are approaches that could lead to 'classitis' or otherwise 'messy' html. I don't mind that though and think the larger the site the more sense this makes. If you're making a 4 page site, maybe don't bother.
But this works for me and may not for you. So I go back to my original statement, there's no right or wrong here :)
Hi all and thanks in advance for your help.
I'm pretty new to the CSS, and I would like to have a good input to start building and learning the fastest way possible. I'm already doing some CSS tests myself. Right on the question.
this is the relative css code (I put it on pastebin because it's a bit long)
CSS CODE
As you can see in the code, the 2 tables showing up in the image, have a background and I had to set their size manually with
width:100px;
height:120px;
in the td.menuleft and td.menucenter classes.
1° Question
How do I make automatically resizing cells?
For example i want to say:
Make table tag wide 100% of the page width, then let me make classes for cell tables that are a certain percentage of the table width.
Example
Pic of my work, and how I want to make it like
This way it will be easy to make up tables into tags to automatically fill pages. I've seen something about positioning (relative, absolute) but I didn't managed to make it work.
2° question
What's the best way to structure a web page with css in general? It's ok to do like I said, a div, with tables inside and place every element in a table like manner?
Or can you give me any guide step to step on how to do a particular template?
Thanks guys.
when you want to learn how to make good and effective design that are also considered any worth by search engines, then don't use tables for layouts. tables are there for showing table data, not layout. Use instead divs and start reading about positions, displays, floats.
That is the way you want to go
If you set the tds to be a certain percentage width, they will be the percentage of the parent. so:
table {
width: 100px;
}
tr {
width: 100% /* Will be 100px */
}
td.quarter {
width: 25%; /* Will be 25px */
}
td.half {
width: 50%; /* Will be 50px */
}
And I agree with the previous poster, do NOT use tables for layouts. Not that you are doing that here. But for layouts stick to divs and such.
So I have a simple page:
www.kensandbox.info/centerthis
This is a simple html/css page and I'm trying to add a paypal button.
The problem is that I can't figure out how to center the button? I've tried adding the following:
<div align="center"> form code here </div>
No dice. I've even tried adding the center tag before the form.
The site code (simple html and css file) can be downloaded here:
www.kensandbox.info/centerthis/centerthis.zip
My guess is that one of the other CSS elements is overriding my change.
What am I missing?
Thanks
there is a float:left in form input, form .btn inside mycss.css
Add float:none to that input if you want to override.
Without looking at your code I would say the best way to center a div is usually make sure it's displayed as a block element (should be by default) and that its width is specified; then finally apply margin: auto.
e.g.
<div class="container">
...
<div class="centered-element"> form code here </div>
...
</div>
where
container {
width: 200px;
}
centered-element {
width: 150px;
margin: auto;
display: block; /* to make sure it isn't being mucked up by your other css */
float: none; /* to make sure it isn't being mucked up by your other css */
}
Edit:
I say to do it this way because, like I now see someone has commented, <div align="center"> is deprecated and so is the <center> tag. To expand, this is because your HTML should only be used to create the structure and semantics of your web page, and CSS should be used for the presentational aspects of it. Keeping the two separate as best as you can will save you a lot of time in the long run.
Also it's best to design your CSS in a way where you shouldn't have to set display: block; on a div (because a div is already a block element) and your shouldn't have to unset a float by using float: none;. For more on a good way to do that, improve your workflow, save yourself some time, and generally be awesome, check into object-oriented CSS a.k.a. ooCSS
I found the answer and I want to thank the two individuals who took the time to answer.
The thing I didn't understand is how to look at a web page and see what CSS code was driving the formatting.
Some research lead me to a Chrome plug in named CSSViewer. Using this plugin and the information from the answer I was able to identify a float left css element that I simply had to change to a float center.
Thanks again for the help.
