Slopy Elements with CSS3 It's always a delight to see some non-straight elements in web design. Angled shapes and diagonal lines can create an interesting visual flow and add some unexpected excitement. Inspired by many superb designs that use non-straight elements, I want to show you some simple examples and ways how to create slopy, skewed elements with CSS only. View demo Download source It’s always a delight to see some non-straight elements in web design. So, let’s begin! Example 1 In our first example, we want to have a pretty normal layout with a little twist: we want a diagonal separation between the elements. The Markup Let’s create a section for our whole content and inside we’ll add some divisions with the class se-slope. Now, let’s check our the style. The CSS The body will have the same background color like all the even se-slope elements, which is pink. The divisions will all be rotated: the odd ones will be black and rotated 5 degrees and the even ones will be pink and rotated -5 degrees. Example 2
Filter Functionality with CSS3 Using the general sibling combinator and the :checked pseudo-class, we can toggle states of other elements by checking a checkbox or a radio button. In this tutorial we will be exploring those CSS3 properties by creating a experimental portfolio filter that will toggle the states of items of a specific type. View demo Download source The idea is inspired by Roman Komarov’s brilliant “Filtering elements without JS” experiment where he uses checkboxes and radio buttons for filtering colored shapes. The beautiful Dribbble shots used in the demos are by Mike from Creative Mints. The Markup Let’s start with the markup. The unordered list will contain all the portfolio items as anchors with an image and a span. The CSS We’ll be going through three example effects, but first, let’s take a look at the common style. I will omit all the vendor prefixes, but you will, of course, find them in the files. The main section container will have a specific width: Let’s move on to the item list: Example 1 Example 2
Text Blocks Over Image Someone recently asked me about this technique and my first reaction was that it was probably a little too mundane to cover as a tutorial. But then I got to thinking that there is actually a few interesting things happening here and the style is trendy enough people might be interested. The idea is just to overlay some text over an image, but as blocks that stick out from the left with an even amount of padding all the way around the variable-length text. View Demo The Schematics The HTML <div class="image"><img src="images/3754004820_91a5c238a0.jpg" alt="" /><h2>A Movie in the Park:<br />Kung Fu Panda</h2></div> Putting the image in as a background image of the wrapping div would be easier, but in this scenario I see the images as content, and thus belongs in the HTML. The CSS This is going to put our text right up on top of the image nicely, but it doesn't accomplish the transparent black box we want to achieve behind the text. Let's wrap the inside h2 of the in a span: Problem Share On
Create a Letterpress Effect with CSS Text-Shadow The letterpress effect is becoming hugely popular in web design, and with a couple of modern browsers now showing support for the text-shadow CSS3 property it’s now simple and easy to create the effect with pure CSS. No Photoshop trickery here! Letterpress – Isn’t that a type of industrial print method? That’s right! But the effect has also made its way into web design. With the recent support of text-transform in Safari and Firefox (3.1+) the effect can easily be created without needing to use any image replacement techniques. View demo Start out by creating a simple background. <! <h1>Line25</h1> <h2>Pure CSS Letterpress Effect</h2> Set up a plain HTML document, then add a few lines of text to test the effect on. Style up the text using the usual CSS properties to edit the size and basic appearance. Now we’re ready to apply the text-shadow property. color: #222; text-shadow: 0px 2px 3px #555; Simple!
CSS transform-origin Coming to SVG Defining CSS Shapes with the circle, rectangle, and ellipse shape functions is easy and pretty effective if what you want are circles, rectangles or ellipses. For more complex shapes you can use the CSS polygon function. However enumerating a polygon's vertices can be tedious. Tools can take much of the pain out of the task, but it still tends to be a slow process. It's often the case that complex shapes are intended to mirror the boundary of an image's (transparent) background. Most of the articles I've written have focused on how the implementation of some recently landed feature works. Image Valued Shape Basics The CSS shape-outside property specifies a shape which inline content must wrap around. An image valued shape is defined with a URL that refers to an image, typically a PNG, or an SVG document: In this case the value of the "image-valued-shape" IMG element's shape-outside property is a local URL called "pipe.png". The shape-outside Property and float:left, float:right
Original Hover Effects with CSS3 The power of CSS3 is enormous and in this tutorial we will see how to exploit it in a very creative way. We are going to create some thumbnail hover effects with CSS3 transitions. On hover over a thumbnail, we will reveal some description of the thumbnail, using a different style in each example. View demo Download source Please note that this will only work properly in modern browsers that support the CSS3 properties in use. The Markup The structure of markup is very simple and intuitive. Inside the view insert an element with the class mask that will be responsible for our effects driven by CSS3 and inside it we will put a title, description and a link to the full image. <div class="view"><img src="image.gif" /><div class="mask"><h2>Title</h2><p>Your Text</p><a href="#" class="info">Read More</a></div></div> The CSS After creating our markup we’re going to set our style. And now we’ll look at the ten effects. Example 1 And now comes the heart of our effect. Example 2 Example 3 Example 4
Circle Hover Effects with CSS Transitions From our sponsor: Get started on your Squarespace website with a free trial In today’s tutorial we’ll experiment with hover effects on circles. Since we have the border radius property, we can create circular shapes and they have been appearing more often as design elements in websites. One use that I especially enjoy seeing is the circular thumbnail which just looks so much more interesting than the usual rectangular. And because the circle is such a special shape, we are going to create some special hover effects for it! Please note: the result of this tutorial will only work as intended in browsers that support the respective CSS properties. We will omit vendor prefixes in this tutorial. So, let’s get started! The HTML For most of the examples, we’ll be using the following structure: Although we could use images here, we’ll give ourselves a bit more freedom by using background images instead. Now, let’s make some hover effects! The CSS Example 1 And now, the interesting hover action!

Standardista La fusion des marges en CSS Qu’est-ce que la fusion des marges? La fusion des marges est un mécanisme décrit dans la spécification CSS (CSS 2.1: Collapsing Margins). Il concerne les marges verticales (margin-top et margin-bottom) des éléments de type bloc. C’est un mécanisme qui, pour deux blocs qui se suivent, «fusionne» la marge inférieure du premier et la marge supérieure du deuxième. <p style="margin-bottom: 20px;"> Premier paragraphe </p><p style="margin-top: 30px;"> Deuxième paragraphe </p> Pourquoi ce mécanisme? La fusion des marges est très utile pour obtenir des espaces harmonieux entre les portions de texte. la marge supérieure correspond au retrait minimal souhaité avant l’élément; la marge inférieure correspond au retrait minimal souhaité après l’élément. Voici par exemple un code CSS simple qui exploite ce mécanisme, pour obtenir des espaces harmonieux entre les paragraphes: Fusion des marges entre un élément et son parent Exemple simple de fusion des marges enfant—parent Nous obtenons le résultat suivant:
Display inline-block, une valeur trop peu utilisée Floatera, floatera pas… mais pourquoi ne pas utiliser la valeur inline-block de la propriété display en CSS ? Vous connaissez certainement les valeurs block ou inline, mais moins celle de inline-block et pourtant elle peut vous servir dans bien des cas. Voyons dans quelles conditions nous pouvons l'utiliser (de manière non exhaustive) dans un premier temps, puis dans un second temps quelques difficultés dans son utilisation. Cette astuce a été publiée initialement sur le blog personnel de l'auteur, creativejuiz.fr à la date du Jeudi 17 mars 2011. Utiliser display: inline-block Par défaut les éléments input ont comme valeur de display celle de inline-block. Le formulaire Quelle transition ! Je vous propose cette forme de mise en page pour formulaire. Notre code CSS va donc nous permettre d'avoir un comportement homogène. La CSS : Aperçu du formulaire Une navigation horizontale (éléments de liste) Le code HTML : Le code CSS : Remarque : la valeur inline sur le li est suffisante dans mon exemple.
