Very few websites work on portable devices without causing problems for users. However, users browse the web using portable devices. It is therefore important that websites work on these devices. The Opera browser is designed to work on portable devices. In Pocket-Sized Design, Elika Etemad and Jorunn D. Newth provide details on creating a style sheet for portable devices. The main constraint of a portable device when browsing the Internet is its small screen, which may be only one hundred and one width. twenty pixels, as well as a possible inability to scroll horizontally. Other constraints are different input methods, limited memory, slow processors, and slow and expensive downloading. To accommodate the constraints of a small screen, coders and designers must reduce the size of aspects of their web pages. To begin with, for portable devices there should be no more than one column of text on the screen. This can be achieved by using CSS only to style one's website, instead of tables or frames for layout, as CSS has the potential to style. the XHTML while it remains in a single column when viewed without CSS. This does not necessarily have to restrict the design for people viewing the site on computer screens, as one can list a stylesheet specifically for handheld devices, as well as other user agents, and let visitors Computer screen elegant design in so many columns. This pleases both the designer and the user. Using pixels in the handheld style is also not recommended, because even a few pixels can take up a lot of space on a device that is, say, one hundred and twenty pixels wide. Instead of pixels, use ems or percentages, as both scale better. You should also use smaller margins......in the middle of the paper......e stylizes it, then it is easy to change it, which leaves more space for, for example, reworking the layout of a portable device. In order to tell a browser like Opera that a stylesheet is available so it can use it for portable devices, the coder must specifically mark the stylesheet as for portable devices. To do this, "handheld" must be specified as the media attribute, or must be included with an @media or @import rule. For a web designer or coder to create a design for wearable devices, there are many rules to follow. follow. Making elements smaller and more flexible is the first thing a coder should do. These days, as more and more people browse the web on portable devices, it is increasingly important to design for these devices, as well as the computer screen. com/articles/pocket
